Study On The Mechanical Behavior Of Openings Filled Wall-Steel Frame

Filled wall-steel frame structure is widely used in building structure, In practical engineering applications, As the functional requirements will inevitably open the hole in the wall on. Wall openings must lead to bearing capacity, seismic performance degradation,It makes openings infilled steel frame for the situation different from the entity filling wall-steel frame and the bare steel frame. Filled wall-steel frame structure was extensively studied by scholars at home and abroad, But openings infilled-steel frame is very limited research. Therefore, the research to the force of its mechanism and capacity have theoretical and engineering significance.Building nonlinear finite element models using ANSYS program,And in the light of previous experimental to verify the correctness in the article.Through four series of 12 specimens of the calculation and analysis,The paper research the performance and failure mechanism of openings infilled-steel frame under monotonic and cyclic loads. Considering openings filled wall-steel frame properties by changing the hole size and location parameters. Some useful conclusions are obtained.
