部分预应力混凝土延性梁的试验研究

AN EXPERIMENTAL STUDY ON PARTIALLY PRESTRESSED CONCRETE DUCTILE BEAMS

本文介绍了配置有较密箍筋的部分预应力混凝土延性梁在大变形领域的多次重复载荷作用下的试验概要,并对该梁的破坏过程、混凝土受压破坏的几个应变值、荷载一位移滞回曲线的特性、延性、塑性铰区域内外的变形特性等试验结果作了若干讨论。

In this paper the experimental work of partially prestressed concrete beams is described,in which the beams confined with lateral reinforcement are subjected to high intensity reversed cyclic load,and a part of experimental results are discussed which include the failure process,the typical compression strains of concrete,the deflection behavior,ductility and the deformation characteristics in the equivalent plastic hinge zone.
