基于状态方程法的钢筋混凝土梁桥随机地震反应概率分析

The probability analysis of random seismic response for reinforced concrete beam bridge based on state equation method

钢筋混凝土梁桥在地震作用下结构可简化为一多自由度体系,基于状态方程法的一般原理,推导了钢筋混凝土梁桥的自由振动解和强迫振动解,并对结构在平稳白噪声激励下进行了随机地震反应分析。

The reinforced concrete beam bridge is simplied multi-degree freedom system under earthquake. The free vibration and forced vibration solutions are deduced based on principle of state equation method. The random seismic response of structure is analysised under stationary white noise input.
