［摘要］某招商中心采用單層球面網(wǎng)殼結(jié)構(gòu)，球形外立面直接落地，表面開有三處大門洞，形成結(jié)構(gòu)的薄弱點。著重介紹了開孔單層網(wǎng)殼的方案選擇、支承體系、設(shè)計荷載以及強(qiáng)度和整體穩(wěn)定計算等。設(shè)計根據(jù)強(qiáng)度條件初步確定截面以后，應(yīng)進(jìn)行非線性全過程屈曲分析，并考慮初始缺陷的影響程度來綜合確定球殼的極限承載能力。

Design of single layer spherical latticed structure of merchant center

Yang Wei, Huo Wenying, Zhang Shitong(China Architecture Design & Research Group, Beijing 100044,China)

Abstract:The single layer spherical latticed structure is used in a merchant center. The spherical dome covers the ground directly. Three gates are opened in the dome and become the weakness of the structure. The scheme selection，support system，design load，strength and global stability of the holed-single spherical dome are introduced. The nonlinear buckling analysis should be done after the sections of members are decided according to the strength of materials, and the original disfigurement should be considered to calculate the ultimate bearing capacity of the spherical dome.

Keywords:holed-single spherical dome；dynamic response；seismic design；buckling analysis
