摘要
通过建立混凝土简支矩形小挠度薄板受横向干扰时弹性力学的数理方程,解出方程的挠度函数,以此对其振动波形、波形衰减周期、最大振动反应及其时间等振动特征进行分析,并与静力分析的解比较,阐述了横向干扰混凝土简支矩形等厚薄板工程应用问题的若干基本观点。
by establishing mathematical equations on the simple support rctangular small deflection thin concrete plate of lateral interference, its oscillation waveform and waveform decay cycle and maximum vibration response and vibration characteristics of its time are analyzed on a solution the equation, and static analysis solution for comparison. It addresses several basic views on lateral interference of thin concrete plate of rectangular small deflection during the engineering application.
