部分预应力混凝土框架性能试验研究

The Test and Study on Behavior of Partially Prestressed Concrete Frames

<正> 目前,部分预应力混凝土(简称 PPC)框架结构在我国正得到越来越广泛的应用,但在该结构的设计中,诸如弯矩重分布、预应力对节点区的影响、反复荷载下的荷载挠度关系等问题有待进一步研究,因此,本文进行了针对上述问题的试验研究.

In this paper,based on experimental results of 3 partially prestressed concrete(PPC) frames,the serviceability and moment-bearing capacity of PPC frames are studied.And the behavior of beam-column joints,the moment redistribution and the relations between load and deflection under recycle loading of PPC frames are conducted.
