摘要
本文通过对高架道路中间隔离护栏的冲击试验研究和理论计算给出了交通工程中常遇车辆冲击作用下的混凝土梁中钢筋应变变化率的最大值估算 。
In this paper, the evaluation of steel variance ratio in concrete members under impact loading is deduced with the impact test and theory analysis of the guardrail, which provides necessary basis for further research on the dynamic response characteristic of structural members in civil engineering.
