民居建筑钢结构框架受到腐蚀后的抗震性能问题引发了关注,为了分析锈蚀对于程度民居建筑钢结构框的影响,在极限承载力模型的基础上对民居建筑钢结构框架抗震性能进行试验分析。制作民居建筑钢结构试件,设定轴压比、钢材规格和钢材强度,拟定腐蚀程度,确定试件截面尺寸。人工进行试块加速腐蚀,获取各种腐蚀程度的试块,再对其进行极限承载力测试并得到相应模型,最后按照模型计算震动模拟参数,得到各种腐蚀程度下试块的抗震结果。结果表明:未腐蚀试件滞回曲线呈现饱满弓形,耗能较高,抗震性能更强。与不同腐蚀程度试件相比,屈服前的滞回曲线线性变化更明显,抗侧刚度稳定,弹性较强。发生屈服之后,极限承载力保持在恒定状态,屈服后的刚度值可取0,延性系数增加,延展性更好。轻度腐蚀和中度腐蚀试件的指标有所下降,但是都标准允许范围之内。

The seismic performance of the steel frame of residential buildings after corrosion has attracted attention. In order to analyze the influence of corrosion on the steel frame of residential buildings, the seismic performance of the steel frame of residential buildings was tested and analyzed on the basis of the ultimate bearing capacity model. To make the steel structure specimens of residential buildings,the paper set the axial compression ratio, steel specifications and steel strength, formulated the corrosion degree, and determined the cross-section size of the specimens. The accelerated corrosion of the test blocks was carried out manually, and the test blocks with various corrosion degrees were obtained. Then the ultimate bearing capacity of the test blocks was tested and the corresponding model was obtained. Finally, the vibration simulation parameters were calculated according to the model,and the seismic results of the test blocks with various corrosion degrees were obtained. The results show that the hysteretic curves of the uncorroded specimens shows a full bow shape,with higher energy consumption and stronger seismic performance. Compared with the specimens with different corrosion degrees,the linear change of hysteresis curve before yield is more obvious, the lateral stiffness is stable, and the elasticity is strong. After yielding,the ultimate bearing capacity remains at a constant state,the stiffness value after yielding can be taken as 0, the ductility coefficient increases, and the ductility is better. The indexes of mild corrosion and moderate corrosion specimens decrease,but both are within the allowable range of the standard.
