摘要
钢筋混凝土板在低速冲击下的局部与整体变形和破坏的特点主要取决于冲击的初速和接触区直径与结构厚度的比值 ,在计算中必须既考虑冲击的局部作用 ,也须考虑其整体作用。本文既给出了钢筋混凝土板在低速冲击下局部变形评估方法 ,又给出了整体变形的弹塑性工程近似分析方法 ,整体变形分析中忽略板在裂缝形成前的工作阶段 。
Characteristics of reinforced concrete slabs to low velocity impact depend mainly on the velocity of projectile and the ratio of diameter of contact zone to the thickness of structures. The method of evaluation was given for the local deformation of reinforced concrete slabs to low velocity impact, and the elasto-plastic method was presented for the total deformation neglecting the process before cracking and taking both processes into account before and after yielding of the reinforcing bar.
