Experimental Study on Load Bearing and Deformation Mechanism and Structural Performance of Cnatilever Type Prestressed Concrete Beams with Different Connecting System (compressed or unit type) and PC Tendon Type (round or deformed)

Abstract

This study aims to obtain useful basic data for design performance of prestressed concrete (PC) structures and creating macro-models of prestressed concrete beams. It deals with the investigation of effects which various factors such as connection type (compressed type, unit type), PC tendon type (round or deformed), lateral reinforcing steel quantity, etc. would have on various characteristics such as rotational angle distribution of plastic hinging region, PC tendon strain distribution, lateral reinforcing steel strain distribution, crack pattern, plastic hinge length, etc. It further reports on load baring and deformation mechanism for PC beams with different connecting system and PC tendon type.
