The probability analysis of random seismic response for reinforced concrete beam bridge based on state equation method
【摘要】 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。
【Abstract】 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 ran-dom seismic response of structure is analysised under stationary white noise input.
