双塔斜拉桥的实用简化分析

【摘要】 本文根据双塔斜拉桥的结构特点,将斜拉桥拟成一根弹性地基梁,据此来推导车辆荷载作用下产生的内力和变形。该方法通过验证认为是一个简捷有效的方法,可供设计人员参考。更多还原

【Abstract】 According to the structural characteristics of double pylons cable-stayed bridges, we sinplify the main girders as a beam on elastic foundation. Depending on this, intenal forces and displacements, caused by lived load, are developed. Through the example, the method is verified a short - cut way, and it may give the design engineers a simple design tool to estimate the intermal forces.更多还原
