摘要
在不同荷载下进行高层建筑等效随机静风载荷性动态监测,提高高层建筑的力学监测和分析能力,有效指导高层建筑施工和设计。本文提出一种基于反演积分应力补偿的高层建筑等效随机静风载荷评估模型,构建不同荷载下高层建筑的应力屈服响应特征方程,以应力参数、屈服响应、控制力矩等参数为控制约束参量,进行高层建筑的荷载与应力屈服响应性的最佳匹配控制,以测量的力学参数和惯性力矩为输入进行模糊决策控制,采用反演积分应力补偿方法进行随机静风载荷性评估,实现不同荷载下的高层建筑等效随机静风载荷测试和应力控制。运用ANSYS软件进行力学分析,仿真结果表明,采用该方法进行高层建筑等效随机静风载荷评估的准确性较高,过程收敛性较好,测试结果的泛化能力较强。
Under different loads,the dynamic and static load monitoring of high-rise building is carried out,and the ability of mechanical monitoring and analysis of high-rise building is improved,and the construction and design of high-rise building are effectively guided.An equivalent stochastic static wind load assessment model for high-rise buildings based on inverse integral stress compensation is proposed.The characteristic equation of stress yield response of high-rise building under different loads is constructed.The stress parameter,yield response and control moment are the control parameters,and the optimal matching control between the load and stress yield response of high-rise building is carried out.Fuzzy decision control is carried out by taking measured mechanical parameters and inertia moment as input,and stochastic static wind load evaluation is carried out by using inverse integral stress compensation method.The equivalent random static wind load test and stress control of high-rise buildings under different loads are realized.The simulation results show that the proposed method is more accurate and convergent in the assessment of equivalent random static wind loads of high-rise buildings,and the generalization ability of the test results is strong.
