摘要: 蘇州國際會議酒店空中連廊為跨度 81m、位于距地面 76.1m 至 95m 高空的大跨度高位鋼結(jié)構(gòu)連廊. 該連廊具有受風荷載與地震作用顯著、與兩側(cè)塔樓的相對運動復(fù)雜等設(shè)計難點. 經(jīng)多種方案對比分析,確定了連體結(jié)構(gòu)采用柔性連接,連廊采用鋼桁架下掛廊橋結(jié)構(gòu)形式,支座布置采用鉛芯橡膠支座+黏滯阻尼器的設(shè)計方案. 通過連廊支座抗風與抗震設(shè)計,驗證了連體結(jié)構(gòu)連接方案的安全性. 基于鋼連廊獨立模型,考慮地震作用在連廊支座處的放大效應(yīng),對連廊鋼桁架的抗震性能、關(guān)鍵節(jié)點受力、防連續(xù)倒塌性能與樓面舒適度進行了設(shè)計復(fù)核,驗證了該連廊結(jié)構(gòu)方案的安全性與適用性.

Abstract: The corridor of Suzhou International Conference Hotel is a large-span steel corridor in high position with a spanof 81m and an altitude of 76.1m to 95m from the ground. Many difficulties exist in the design of the corridor, such assignificant wind and earthquake effects, and complex relative movement between the corridor and towers. After comparativeanalysis of various design schemes, it was determined that flexible connection was adopted for the connected structure, thestructural form of steel truss hanging bridge was used in the corridor structure, and lead rubber bearings with viscousdamper were arranged in the bearing supports. The security of connection scheme of the connected structure was verified bywind and seismic design. Based on the independent model of the steel corridor, considering the amplification effect ofseismic action at the corridor support, the seismic performance of the steel truss of the corridor, the stress condition of keynodes, the continuous collapse prevention performance and the floor comfort were reviewed. The results validate the safetyand applicability of the above corridor structure scheme.
