［摘要］魯臺(tái)經(jīng)貿(mào)會(huì)展中心主體采用框架-剪力墻結(jié)構(gòu)，包括展覽區(qū)、商業(yè)區(qū)、共享大廳等多個(gè)功能區(qū)。各功能區(qū)通過(guò)蒙皮網(wǎng)殼連接形成整體。鋼結(jié)構(gòu)與混凝土結(jié)構(gòu)相互交錯(cuò)，涉及的鋼結(jié)構(gòu)有桁架、單層網(wǎng)殼、雙層網(wǎng)殼等多種形式。整體結(jié)構(gòu)是一個(gè)復(fù)雜的超限工程。采用基于性能的設(shè)計(jì)方法，對(duì)重要構(gòu)件提出專(zhuān)門(mén)的性能目標(biāo)。對(duì)展廳大跨度樓層鋼結(jié)構(gòu)進(jìn)行了活荷載不利布置分析。重視鋼結(jié)構(gòu)的穩(wěn)定設(shè)計(jì)，通過(guò)多種構(gòu)造措施和計(jì)算分析保證了鋼結(jié)構(gòu)的整體穩(wěn)定。對(duì)整體結(jié)構(gòu)進(jìn)行了動(dòng)力彈塑性分析，考察了結(jié)構(gòu)的塑性發(fā)展程度和變形能力，并對(duì)薄弱構(gòu)件進(jìn)行了加強(qiáng)。設(shè)計(jì)結(jié)果表明，結(jié)構(gòu)抗震性能良好，結(jié)構(gòu)體系安全可行。

Abstract:The frame-shear wall structure was adopted in Shandong-Taiwan Exhibition Center in Weifang city, which includes exhibition areas, commercial areas, public hall, and other functional areas. All functional areas are covered under latticed skin shell. The steel structures include the steel truss, single-layer shell and double-layer shell. The structure is complicated beyond the scope of Chinese Code for seismic design of buildings. Using performance-based design method, the performance objectives of the important components were proposed. The large-span steel truss was analyzed, considering unfavorable live load distribution. The stability design of steel structure was paid attention to, and a variety of structural measures and computational analysis were taken to ensure the stability of steel structure. The dynamic elastic-plastic analysis were executed. The structural plastic performance and deformation were evaluated, and the weak component was enhanced. The results show that the performance of the structure is good, and the structure system is safe and reliable.
Keywords:steel truss; latticed shells; performance based seismic design; stability analysis; nonlinear time-history analysis
