Abstract


Application and Research of Steel for nearly a hundred years of history, theory increasingly sophisticated technology matures. However , with regard to considering infilled steel frame buildings in the lateral force component acts as a problem of domestic and foreign research are relatively limited , there are many problems remain unresolved , while China's steel specification did not specifically related to this area content. All aspects of the study showed that infill walls in infilled steel frame structure can play a role in resistance to lateral forces , it can become an important part of the structure . Therefore its force mechanism and capacity of research has important theoretical significance and engineering reference value. ASA material is a new type of energy saving light composite materials with good mechanical and physical properties as well as a strong weather resistance and good fire resistance . For infilled steel frame structure can enhance the lateral load resistance of the structure , but also can reduce the structural weight . This article describes the ASA mosaic infilled steel frames under low cyclic loading tests , mainly for the following three aspects: 1 . Through theoretical analysis, design, test , completed the three -bay steel frame full-scale model test and ASA hole inlaid wood board test. Obtained by experiments at low infilled steel frames under cyclic loading hysteretic behavior , stiffness relationships , failure mechanism , ductility , energy dissipation mechanism and other characteristics, and with the same size of pure steel frame and window and door openings to fill wall steel frame made ??comparative analysis of relevant characteristics ; P-Δ2. using ANSYS finite element software , the establishment of a pilot model , the impact of the test results in the presence of various factors were analyzed ; deduced using the theory with padding wall steel frame effect equivalent lateral force resisting system of cross- braced steel frame system supporting the cross-sectional area in the formula obtained test results verified. 3 aspect ratio for infill walls , infill walls with steel frame and steel shear connectors within the framework of the interfacial friction and other effects infilled steel frames infilled lateral load resistance factors are discussed, and pointed out that these effects considered in the design factor for overall performance and the control structure is designed to vital. Finally , at the conclusion thesis based on the work presented in this issue resolved yet .
