Abstract

一种基于全索系索力测试和误差自适应分析的损伤判定方法，用于测量预应力钢结构中的预应力拉索（1）索力，并通过对拉索（1）索力测试误差的自适应分析确定可能损伤的拉索（1）及其位置，方法包括：放置激光测速仪（4）；用激光测速仪（4）测量该拉索待测点（P）的速度；计算出拉索（1）的索力；计算出整个预应力钢结构内所有的拉索（1）之间的索力；分析测试索力的误差并且找出可能出现损伤的拉索（1）以及与其相连接的拉杆（2）。该方法可同时获取拉索（1）在面内竖向与面外横向的动力响应特征，进而获得自验证的索力分析结果，并根据索力误差自适应分析，确定索系中可能出现损伤的拉索（1）及其位置，为复杂的预应力钢结构索力测试与损伤判别提供有效依据。
