配筋砌体墙混凝土框架内力分析与裂缝模拟

摘要

利用有限元方法，对空框架、空心砌体墙框架、实心砌体墙框架、配筋砌体墙框架四种有限元模型进行对比分析，结果显示：空心砌块、实心砌块、配筋砌块的加入显著提高了混凝土框架结构的极限承载力，而降低了结构的延性，改变了结构的破坏形式。%In this paper,four finite element models are analyzed in contrast by using the finite element method,which include the empty frame, hollow masonry wall frame,solid masonry wall frame,and reinforced masonry wall frame. The results show that the hollow block,solid block and reinforced block can significantly improve the ultimate bearing capacity of reinforced concrete frame,while the ductility of the structure can be re-duced,and the failure form structure can be changed.
