Abstract
Bridges with different geometrical configurations have been searched with linear finite element analysis. The aim is to find the position and value of critical proof load. Four different parameters, namely span length, width, skewness and thickness ratio, their influence on proof load are found. In total, 166 sets of data are obtained by performing more than thousands of finite element analyses. Formulas for calculating critical position factor kp and equivalent loading factor kq are obtained by these data and they are approved to be capable enough to predict the results.
