梁端垫块局压应力分布及有效支承长度测定

Local stress distribution and effective supporting length on beam pan measuring

针对规范中未给出梁端刚性垫块上的有效支承长度计算方法，通过试验方法测定了梁端刚性垫块上、下表面局压应力分布，从而给出了有效支承长度计算公式。又通过有限元分析，得出了梁端垫块上的有效支承长度计算值与试验值的对比，并验算常用进深的有效支承长度，分析得出其简化计算公式。

： In the light of the code that didn't give the counting formula of the effective supporting length on rigid beam pan, this paper tested the local stress distribution upper and under rigid beam pan and put forward a counting formula on effective supporting length that is analyzed by finite element methods with the testing value. According to calculating the effective supporting length of common depth beam, a simplified counting formula was put forward.
