Abstract
The present paper is to introduce a newly proposed method for nonlinear torsional analysis of precast prestressed concrete member with joint by using the Rigid Body-Spring Model. Particular attention in the analysis is focused on the cracking torque, the ultimate strength and the post-cracking torsional behavior for the whole range of prestressing. And also, this work involves comparison between the theoretical analysis results and the experimental data up to failure with consideration of various factors affecting the torsional behaviors. From these results to domonstrate the applicability of the proposed method, it is found that this method is capable not only of prediction of both the pre- and post-cracking torsional behavior but also of analysis of the failure mechanisms in joint.
