EFFECT OF TORQUE IN REINFORCEMENT OF PRECAST CONCRETE MEMBERS

摘要

In this paper two types of precast concrete beam connections have been organized, such as: (1) Encastre end condition. (2) Two types of real connection to the precast concrete column. These are considered before cracking the concrete and after cracking the concrete surface. The results have shown no influence of load on the reinforcement before cracking the concrete, after cracking, the strain in the reinforcement were increased with apply loading followed by exceeding of yield strength in some longitudinal and shear reinforcement. In the other hand there was no significant increase of strain in reinforcement for the joint without top connection which failure occurred in the joint.
