半刚接钢框架内填暗竖缝混凝土剪力墙结构的简化滞回分析模型
Composite inclined strut hysteretic model for partially-restrained steel frame with concealed vertical slit reinforced concrete infill walls
摘要
Abstract
To solve numerical simulation of partially‐restrained (PR) steel frame with concealed vertical slit reinforced concrete (RC) infill walls (PSRCW) in the engineering design stage ,a simplified compo‐site inclined strut hysteretic model was proposed based on the experimental phenomena ,the cracks distri‐bution of RC infill w all ,and the transferring mechanism of PSRCW .T he simplified composite inclined strut hysteretic model of concealed vertical slit RC infill wall was simulated via two parts .The main diagonal inclined strut was used to reflect the transferring lateral force by the contribution of the thick‐ness of concealed vertical slits .The wall‐column part was to simulate the mechanical behavior of slit walls .The effective width of the main diagonal inclined strut was deduced through the internal mechanism of the concealed vertical slit RC infill walls ,and the cyclic restored force model of the main diagonal inclined strut was deduced based on the stress vs .strain relationship curves of concrete .In addition ,the comparison between the results of calculation using the composite inclined strut hysteretic model and those of corresponding tests showed good agreement .关键词
