结构性能的混凝土拱桥减震方法研究
|
摘要
基于位移的抗震设计理论应用于混凝土拱桥时,由于混凝土拱桥刚性巨大的特殊性,该理论无法有效的对拱桥进行减震。针对混凝土拱桥,提出了一种基于性能的减震设计思路的新的减震方法——"一种混凝土拱桥变刚度智能减震控制系统"。该方法在地震作用下将改变主拱体系、适当降低拱桥刚度、提高主拱结构变形能力,对拱桥的位移和主拱的受力进行双控。分析表明,该方法在不显著增加位移的情况下可以降低混凝土拱桥在地震作用下的结构内力。
In civil engineering,the aseismic theory based on displacement generally is used in vibration damping design.This theory cannot be applied to reinforced concrete(RC) arched bridges,however,due to the tremendous rigidity of these bridges.To address this situation,a new vibration damping method called an "intelligent aseismic control system with changed rigidity of RC arched bridges" is suggested.With this method,the system of the main arch will be changed,the rigidity lowered,the deformed capability increased,and the displacement and stress can be under double control.When an earthquake occurs,the RC arched bridge stress can be lowered while the displacement is not obviously increased with this method.
