Test Analysis on Hidden Defect in High Falsework and Its Effect on Structural Reliability

摘要：

In China, the safety of high falsework is a worrying problem, and human error is the uppermost reason for the collapse of falsework.In this paper,on the bases of test data of axial forces of vertical bars of the falsework in a construction site, a phenomenon of improper erection of vertical bar (IEVB) is described and analyzed.The effect of IEVB on structural reliability is discussed, and the results show that IEVB will make an order of magnitude increase in the failure probability.The reliability index of the high falsework does not meet the requirement of corresponding code, and more attentions should be paid to the construction of high falsework.
