一、前言为在地震区用钢筋陶粒混凝土做承重结构,须对其强度与延性性能进行研究。为此,我们对8根不同配筋情况的陶粒混凝土梁和2根普通混凝土梁进行了试验,就下面几个问题做了一些探索性研究。 1、关于平截面假定问题; 2、受拉纵筋进入强化段后,钢筋应力分布不均匀情况的分析; 3、陶粒混凝土受弯构件的延性; 4、配置部分高强钢筋后,受弯构件
I. Foreword The use of reinforced ceramsite concrete as the load-bearing structure in the seismic zone must be studied on its strength and ductility properties. For this purpose, we conducted tests on 8 ceramsite concrete beams and 2 ordinary concrete beams with different reinforcement conditions, and made some exploratory studies on the following issues. 1. Regarding the assumption of the plane section; 2. Analysis of the uneven stress distribution of the steel bars after the longitudinal bars are pulled into the reinforced section; 3. The ductility of the ceramsite concrete flexural members; 4. The bending members after the configuration of some high-strength steel bars.
