[摘要] 青島大劇院屋架鋼結(jié)構(gòu)設(shè)計(jì)通過(guò)在不同位置采用固定鉸支座、單向滑動(dòng)支座、雙向滑動(dòng)支座等支承于下部四個(gè)獨(dú)立的混凝土結(jié)構(gòu)單體之上，在實(shí)現(xiàn)屋架傳力途徑的前提下，最大限度地降低了由于下部結(jié)構(gòu)相互獨(dú)立的自振特性所產(chǎn)生的不利影響。本文對(duì)該屋架的溫度應(yīng)力分析、支座形式的選用及布置情況進(jìn)行了詳細(xì)闡述，介紹了屋架鋼結(jié)構(gòu)的整體計(jì)算與分析、典型節(jié)點(diǎn)等，旨在為類似工程提供參考與探討。

Abstract: Through a series of fixed joint supports, and sliding supports either in single direction or in both directions, the steel structure of the roof for Qingdao Crand Theater is based on the four nether concrete structures, which are independent to each other. By this way, the disadvantages, caused by the independent vibration characteristic of the concrete structures, are reduced furthest, while the load transfer routes are achieved already. In this paper, the temperature load, the form and the distributing of the support system are introduced in detail, global calculation and analysis of the steel structure, design of typical joints are presented too.
Keywords: Qingdao Grand Theater; steel roof; sliding supports
