钢筋混凝土结构地震破坏机理的材料分析

在工程结构的抗灾研究中,首要关注的是材料受灾后的性能变化,即灾害对材料物理力学性能的影响,亦即材料在灾害作用下的损伤。文章从分析钢筋混凝土结构受地震作用后的损害机理入手,结合材料内部性能的改变,探讨了结构损害的根本原因,并提出合理有效的改善措施,以减少地震多发区的灾害损失。

Material Analysis of Seismic Failure Mechanism of Reinforced Concrete Structure

In anti-disaster research of engineering structures, the primary concem is the change in mate-rial properties after the disaster, that is the impact of disasters on the physical and mechanical properties of materials,and it is also the material damage under disaster effects.This article started from analyzing the damage mechanism of reinforced concrete structures after seismic impact, and in combination with the changes of internal material properties, it discussed the radical causes of structural damage, and proposed the effective and reasonable improvement measures,aiming to reduce the disaster losses in earthquake-prone areas.
