无阻尼纵桥向限位装置的计算与设计
|
摘要
简述桥梁结构的地震损害,主要是落梁方面,并且总结桥梁的震害的经验教训；简要介绍国内外的防落梁研究概况及本文研究意义和主要内容。国内所采用的限位装置一般只是作为构造措施,没有经过计算和设计,在地震作用下很难起到真正的防落梁效果。本文对设置无阻尼纵桥向限位装置的结构进行大震激励的动力时程分析。在大震作用下的结构中,限位装置装置不但能起到防落梁效果,亦会增大结构的整体性、提高结构的抗推刚度。
经分析计算,得出限位装置的受力及防落梁效果随其刚度、初始间隙、场地土的变化规律,得到本文算例对应的最合理限位装置参数,且针对本论文中的桥梁设计了混凝土挡块。
Briefly introduce the earthquake damage of bridge structure,mainly is to fall beam respect, and sum up the experience and lesson learned from the bridge of the earthquake damage;Briefly describe the general condition of domestic and international anti-fall beam reaserch and significance of this sdudy and the main content.Domestic device of travel limit switch generally used only as structural measures,without calculation and design,very hard to get up the function of anti-fall beam in the earthquake. This paper make dynamic analysis under the arouse of strong earthquake to the structure which is installed no damping longitudinal direction device of travel limit switch.In the structure under strong earthquake device of travel limit switch not only can play defence of fall beam,but also can increase the structural integrity,and can improve the structure's rigidity.
According to analysis,we obtained the law of variation between the force of device of travel limit switch,the effect of anti-fall beam and its rigidity,the initial clearance,site soil,finall obtained the most reasonable limit device parameters for this example,and for this bridge in the thesis desiged concrete block.
