摘　　要：针对采用传统模型进行直墙式建筑物钢框架抗震性模型分析时,由于其结构及受力情况的复杂性,造成得到的分析结果收敛性较差的问题,建立基于塔古奇损失函数的直墙式建筑物钢框架抗震性模型。选取Q235B钢作为抗震性模型的材料,并构建塔古奇损失函数计算震害损伤指数。从分析自振特性和结构变形条件两个角度,进行钢框架结构的离散化处理分析,计算钢框架的极限承受能力与恢复能力,完成对框架极限屈服荷载的受力分析,最终输出直墙式建筑物钢框架的抗震性模型公式。为验证抗震性模型的性能设计对比实验,设置传统的有限元分析模型为实验的对比模型,通过对比实验得出结论:相比于传统抗震性分析模型,设计出的基于塔古奇损失函数的抗震性模型的平均收敛性提高了25. 7%,且使用该模型的建筑物损失程度降低了0. 275%。Aiming at the problem of poor convergence of the analysis results due to the complexity of the structure and the stress situation when the traditional model is used to analyze the seismic resistance model of the steel frame of the straight wall building,the seismic resistance model of the steel frame of the straight wall building based on the tagucci loss function is established.Q235 B steel was selected as the material of the seismic model,and the takucci loss function was constructed to calculate the seismic damage index.From the analysis of natural vibration characteristics and structural deformation conditions,the discrete processing analysis of steel frame structure is carried out,the ultimate bearing capacity and recovery capacity of steel frame is calculated,the ultimate yield load analysis of the frame is completed,and the seismic resistance model formula of steel frame of straight wall building is finally output.Designed for earthquake resistance performance of the models contrast experiment,set up the traditional finite element analysis model for experimental contrast model,through the contrast experiment concluded that compared with the traditional earthquake-resistance analysis model,design of earthquake resistance model based on tower gucci loss function of convergence is improved by an average of 25.7%,and the use of the model building loss rate was reduced by 0.675%.
