摘要：

Seven reinforced concrete horizontally curved beams have been tested. Each beam had a cross section, a radius, and a subtending angle of 90 deg. Each beam was designed to be fixed at both ends and subjected to a concentrated load at midspan. These tests showed that significant redistribution of torsional and bending moments was observed after cracking. It is suggested that elastic analysis of moments should be based on cracked sections. The post-cracking torsional stiffness of curved beams can be reasonably predicted by a theoretical equation derived by the first author.
