15 Proceedings of the 11 th International Conference on New Trends in Statics and Dynamics of Buildings October 3-4, 2013 Bratislava, Slovakia Faculty of Civil Engineering STU Bratislava Slovak Society of Mechanics SAS THE ANALYSIS OF THE CHANGE OF THE SHEAR ANGLE SIN GIRDERS WITH THE SUPPORT STIFF RIB AND SEMIRIGID Witold Basiński 1 Abstract The analysis of the resistance and research of corrugated web girders made of shipped elements framed with sheet metals of end-plate connections indicates the meaning influence of support ribs on critical shearing stresses. In corrugated web girders with support ribs can be sheet metals of end-plate connections. The present paper shows experimental research of the influence of the bending stiffness of support sheet metals on change of the shear angle of the web. Experimental research was conducted on two groups of models made of WTA, WTB and WTC girders, heights: 1000 and 1500, made of shipped elements joined by end-plate connections. The girders were loaded symmetrically by two concentrated forces. The static equilibrium paths of the shear angle P(γ) were determined. It was demonstrated that correct designing of SIN girder ends influenced on change sizes of the shear angle of the web and consequently raising of critical shearing stresses. Słowa kluczowe dźwigary SIN, kąt odkształcenia postaciowego, żebro podporowe 1 WPROWADZENIE Analiza nośności postaciowej [1, 2, 3, 4, 5] oraz badań dźwigarów z falistym środnikiem zbudowanych z elementów wysyłkowych obramowanych blachami połączeń doczołowych wskazuje na znaczący wpływ żeber podporowych na krytyczne naprężenia styczne środnika dźwigarów SIN a tym samym zmianę kąta odkształcenia postaciowego. W dźwigarach z falistym środnikiem rolę żebra podporowego pełnią blachy połączenia doczołowego. W tym celu przeprowadzono badania doświadczalne dwóch grup modeli wykonanych w skali 1:1 swobodnie podpartych dźwigarów SIN złożonych z elementów wysyłkowych o wysokościach 1000 i 1500 łączonych poprzez połączenia doczołowe. Na podstawie badań wyznaczono ścieżki równowagi statycznej kąta odkształcenia postaciowego P(γ). Pokazano, jak wpływ sztywności giętnej podporowych blach czołowych wpływa na zmianę wielkości kąta odkształcenia postaciowego środnika dźwigarów SIN a tym samym na podniesienie krytycznych naprężeń stycznych. 2 BADANIA DOŚWIADCZALNE W celu zbadania wpływu sztywności żeber podporowych na zmianę kąta odkształcenia postaciowego oraz podniesienie krytycznych naprężeń stycznych modele badawcze podzielono na dwie grupy. Pierwszą grupę modeli badawczych stanowiły trzy dźwigary złożone z elementów wysyłkowych o długości 3175 i 1500 mm z podporowymi blachami czołowymi grubości 25 mm spełniającymi funkcję żeber podatnych (rys 1 a). W drugiej grupie przebadano cztery modele badawcze pokazane na rysunku 1b. Dźwigary złożono 1 Dr inż. Witold Basiński, Silesian University of Technology, Gliwice, ul. Akademicka 5, ,witold.basinski@polsl.pl ~ 5 ~
16 z elementów wysyłkowych o długościach 2175 i 1500 mm. W celu zwiększenia sztywności żeber podporowych do czołowych bach podporowych dokręcono teowniki. Boczne żebra teowe o przekroju pokazanym na rys. 1 d przykręcano do dźwigarów bez użycia sprężenia. Środniki modeli I i II grupy dźwigarów wykonano ze stali S235, natomiast pasy ze stali S275. W połączeniach elementów wysyłkowych I i II grupy modeli dźwigarów dano blachy czołowe grubości 25 mm. Elementy wysyłkowe badanych modeli dźwigarów łączono poprzez połączenia doczołowe na śruby. Doczołowe połączenia śrubowe sprężono za pomocą śrub M 24 klasy a) c) b) d) Fig. 1.

Wielkości kąta odkształcenia postaciowego γ określono na podstawie pomiaru zmiany długości przekątnych oraz boków ramy pomiarowej (fig. 2) począwszy od obciążenia P = 0 kn aż do wartości granicznej obciążenia. Fig. 2. Zmiana kąta odkształcenia postaciowego γ w środniku falistym Na rys. 3a pokazano przykładową SRS P(γ) kąta odkształcenia postaciowego modelu dźwigara M 1.21 z podporową blachą czołową 300x25 mm, a na rys. 3b z podporową blachą czołową 300x25 i dokręconym teownikiem do czoła modelu M Na SRS P(γ) obrazujących zmianę kąta odkształcenia postaciowego oznaczono współrzędne punktów charakterystycznych oraz odpowiadające im nośności dźwigarów. Jako kryterium nośności krytycznej V krl środnika przyjęto przejście krzywej P(γ) z liniowej w nieliniową co ~ 6 ~
17 odpowiadało pojawieniu się linii ukośnych załomów plastycznych w falistym środniku. SRS P(γ) sporządzono do nośności granicznej dźwigarów. Punkty charakterystyczne o współrzędnych P 1 (γ 1 ), P 2 (γ 2 ) na rys. 4 rozdzielają przedziały: 0 P 1 (γ 1 ) przedział liniowy czyli odwracalny zmiany kąta odkształcenia postaciowego środnika, P 1 (γ 1 ) P 2 (γ 2 ) nieliniowy przedział zmiany kąta odkształcenia postaciowego czyli formowania się i przyrastania pól ciągnień oraz linii załomów plastycznych w środniku. W obydwu przedziałach kumulują się przemieszczenia od zginania i od sił poprzecznych w środniku. Przedział pomiędzy P 1 (γ 1 ) P 2 (γ 2 ) jest przedziałem nośności nadkrytycznej. W modelach z dokręconym teownikiem usztywniającym żebro podporowe nastąpiło zwiększenie przedziału liniowej zmiany kata odkształcenia postaciowego 0 P 1 (γ 1 ) środnika co spowodowało przesunięcie współrzędnej P 1 (γ 1 ) wskazujące na zwiększenie krytycznej siły poprzecznej. Zakres zmiany kąta odkształcenia postaciowego w zakresie dokrytycznym wyniósł w modelach z podporowym żebrem podatnym od 0,06 0 do 0,08 0. Natomiast w modelach z żebrem usztywnionym teownikiem zwiększył się do 0,09 0 i okazał się zgodny ze zwiększeniem krytycznych naprężeń stycznych sfałdowanego środnika. W zakresie pokrytycznym zmiana kąta odkształcenia postaciowego stała się nieliniowa i zwiększała się do 1 0. a) Fig. 3.

W celu porównania naprężeń krytycznych wyznaczonych na podstawie zmiany kata odkształcenia postaciowego oszacowano naprężenia wynikłe z pomierzonej krytycznej siły poprzecznej. Krytyczne naprężenia styczne wyznaczono z zależności (2) [2]: τ = V h t, (2) kr krl gdzie: V krl pomierzona krytyczna siła poprzeczna, h w wysokość środnika, t w grubość środnika.

Krytyczne naprężenia styczne okazały się w modelach z dodatkowym usztywnieniem żeber podporowych od 11 do 42 % większe w stosunku do modeli żebrem podporowym podatnym. Zwiększenie sztywności podporowych żeber czołowych skutkowało zwiększeniem zakresu zmiany kąta odkształcenia postaciowego w zakresie dokrytycznym a tym samym wzrostem krytycznych naprężeń stycznych falistego środnika. 5 WNIOSKI Dźwigary SIN są ustrojami wewnętrznie statycznie niewyznaczalnymi. Wymiary środnika, pasów i żeber w tym połączeń wzajemnie wpływają na kąt odkształcenia postaciowego oraz naprężenia krytyczne. Zwiększenie sztywności podporowych żeber czołowych wpływa na zwiększenie zakresu zmiany kąta odkształcenia postaciowego w zakresie dokrytycznym. Powoduje zatem zwiększenie przedziału liniowej zmiany kąta odkształcenia postaciowego 0 P1(γ1) środnika, czyli zwiększenie krytycznej siły poprzecznej. Zwiększenie zarówno kąta odkształcenia postaciowego jak i krytycznych naprężeń stycznych dźwigarów z dodatkowym usztywnieniem żeber podporowych w postaci dokręconych teowników wyniosło od 11 do 42%.

23 Proceedings of the 11 th International Conference on New Trends in Statics and Dynamics of Buildings October 3-4, 2013 Bratislava, Slovakia Faculty of Civil Engineering STU Bratislava Slovak Society of Mechanics SAS DYNAMIC RESPONSE OF BUILDINGS AND STRUCTURES DUE TO INDUSTRIAL MACHINERY EFFECTS J. Benat 1 and M. Stehliková 2 Abstract In this paper a dynamic characterization and vibration analysis has been used for the detection and identification of the machine processing condition and the effect of the production machinery vibration on building complex structures and production process. For sensitive process machines and structures dynamic response due to production machinery calculation procedures was applied using experimental input data via spectral analysis. Key Words Industrial machine vibration, ground vibrations, experimental tests, vibration monitoring, spectral analysis. 1 INTRODUCTION In production hall all machines vibrate and, as the state of the machines worsens their vibration level increase and this cause increasing of the structure vibration level, too. An ideal indicator on this state, especially dynamic behavior is obtained via measuring and by supervising the vibration level produced by a machine. While the increase in machine vibration allows us to detect a defect, the analysis of the machine vibration characteristics makes it possible to identify its cause. The analysis in frequency domain is generally carried out when the machine vibratory level is considered to be higher than the acceptable threshold [2]. This kind of vibrations if excessive can damage to nearby buildings and structures and also can negative affect the process in industrial production halls. 2 INDUSTRIAL MACHINERY VIBRATIONS The industrial production machinery process may cause undesirable vibrations transmitted from machine foundations via ground to production hall structures as well as nearby buildings and environment. The ground vibration due to these man activities recorded at a distance from machine foundations is analyzed assuming it to be a random and statistically stationary function of time. This kind of vibrations if excessive can damage to nearby buildings and structures. Vibration which usually also has a negative impact on security and stability of the structures, facilities performance and people should be controlled by experimental analysis and the results compared (spectral picks limit, vibration levels, etc.) with relevant standards prescription values and criteria [3,4]. In the paper case study there is describes the analysis of vibrations caused by unfavorable production machinery effects on hall structures and production process in Justur a.s. St. Turá industrial plant [1]. 1 Prof. Ing.

24 The results of the theoretical and experimental investigation of vibrations caused by production machinery on the buildings structures were analyzed mainly from aspects of the safety of the building structures and the influence of vibrations on production process conditions. 2.1 Assessment of building vibration due to industrial activities Assessment of building vibration due to industrial activities caused by production machines is a problem that can be solved through the application of research. This research consists mainly of defining the relationship between intensity fluctuations in the soil, the vibration energy quantity and the distance from the vibration source. Through intensity fluctuations can appear in different physical quantities, such as the oscillation velocity, acceleration, frequency, ground motion intensity, displacement and energy. There are accessible several standards in the field of measurement of vibration regarding the building vibration limits in the European Union, USA, Australia, ISO codes and others. In Slovakia in the field of measuring and assessing of building vibrations due to ground motion the most commonly used standard is Slovak Standard STN EN /NA/Z1[3] based on EC8 and Slovak Standard STN [4], (In Slovak). 2.2 Machine effects on building structure and production process experimental analysis This paper section shortly described study of the unfavorable production machinery effects on industrial building complex structures and also on vibration sensitive production process in industrial plant of the Justur a.s. St. Tura (company). The complex of industrial processing buildings in the processing building is fully described in [1]. The most sensitive part of the industrial processing buildings is the processing building M1 used for special medical articles production, which is tailored to accurate technological processes. This building is joined with the next processing building M2 by partition wall. The vibrations caused by unfavorable production traditional tool machinery effects in this building disrupted vibration sensitive operations (CNC lathe MORI SEIKI SL 204) in adjacent processing building M1 even they have unfavorable effects on M1 structure with vibration velocities amplitude only v max > 6,0 mm/s. To determine harmful machine vibration sources and to regulate their working regime, it was need to perform experimental measurements and monitoring of the machines related vibrations and compare to the low vibration fabrication machines criteria or relevant Standards. Experimental procedure and device. The industrial processing buildings dynamic response (M1) due to traditional tool machinery in building M2 were measured in relevant structure points by accelerometers BK The output signals from the accelerometers were preamplified and recorded on portable PC equipped with A/D converters of the software packages NI and DISYS, (Fig.1). The experimental analysis has been carried out in the Laboratory of the Department of Structural Mechanics, CEF, University of Žilina [1]. The machines and structure vibrations frequencies were obtained using spectral analysis of the recorded response dynamic components, which are considered as ergodic and stationary.
