［摘要］湖北省图书馆新馆南立面需要形成开敞式门庭，在结构设计时采用设置高位转换层以满足此建筑需要，转换层桁架最大跨度达到40m。结合概念设计和计算分析，对该大跨高位转换桁架进行了三种方案比较，并确定了最终结构布置。具体分析了大转换桁架的有利和不利因素，阐述了为满足转换桁架性能设计目标所采取的分析方法和施工措施。

Abstract: Architects require a big open-style hall in the south elevation of the new Hubei Province Library, so structural engineers have adopted a high conversion layer to satisfy the architectural effect. The maximum span of the conversion trusses reaches to 40m. Combined with conceptual design and computer analysis, a final better structural arrangement of the big conversion truss, which is located at the high conversion layer，has been chosen from three different plans. The specific analysis on advantageous and disadvantageous factors about the big conversion truss was made. Some analytic techniques and construction means were expounded, which is aimed to satisfy the target of performance design of the big conversion truss.

Keywords: conversion truss; support connection; Pushover analysis; lifting and installation
