后锚固锚栓的抗震性能设计

Seismic performance design of post-installed anchors

建筑附属设备比如供水系统、能源系统、电信系统等在地震灾害中常常遭受破坏,甚至中断运转,由此导致的损失是相当大的。后锚固锚栓经常被用来固定以上提到的设备,其合理设计对于确保安全和减小地震造成的成本损失至关重要。介绍了不同类型锚栓的工作原理、地震作用下的性能及抗震承载力设计方法。

Building attached facilities like water,energy or telecommunication supply systems are easily damaged during earthquake action.The economic lost is huge due to malfunction,even stop running of these equipments.Post-installed anchors are often used to fix these mentioned types of equipment,their adequate design is of crucial importance to guarantee safety and minimize costs associated with seismic events.The working principle,seismic performance and design method of these qualified anchors were introduced.
