摘要:

提出分区最小二乘法用于计算含加强层框架核心筒结构的水平位移,并利用数值模拟验证该方法的可行性.与已有的矩形法和梯形法对比,并讨论不同测点布置对计算精度的影响.研究结果表明:分区最小二乘法具有布点少、精度高的优点.将该方法成功应用到某一超高层的实际监测中,得到风荷载作用下各楼层质心处的层间位移角曲线和水平位移曲线,从而为其响应预测、性态评估和结构可靠度分析提供重要的依据.

Abstract:

A novel subregional least square method was presented for horizontal displacement calculation of frame core-tube structure with strengthened stories. The rationality was validated by numerical simulation. Rectangular method and trapezoidal method were used to perform comparison. The effect of different layout of clinometers on the calculation accuracy was discussed. Results show that the subregional least square method can use less clinometer and obtain more accurate results. The proposed method was successfully applied on a super-tall building, in which story drift curve and horizontal displacement curve of each floor were obtained under wind load. This method provides an important basis for the prediction of structural response, the assessment of structural condition and the reliability analysis of structure.
