［摘要］某銀行主樓與裙房之間設(shè)置了下部挑空3層的中庭，4層的行政餐廳采用鋼桁架來(lái)實(shí)現(xiàn)中庭大空間的建筑功能要求，中庭連廊平面呈梯形。通過(guò)計(jì)算，對(duì)每榀桁架進(jìn)行了多方案比較，最終確定了最優(yōu)的截面布置。通過(guò)桁架整體計(jì)算，對(duì)桁架固定支座處存在的水平力進(jìn)行了分析，并采用了合理的節(jié)點(diǎn)設(shè)計(jì)以及合適的加載方式，充分考慮了水平力對(duì)結(jié)構(gòu)的影響，完成了鋼桁架的結(jié)構(gòu)設(shè)計(jì)。

Abstract: A three-layer-high atrium space is located between skirt building and the main building of a bank. The administration restaurant at the fourth floor, which forms a ladder shape, adopts steel truss structure to realize architecture requirements of large space in atrium. Different steel truss arrangements were compared through analysis to determine optimal cross-section layout. Through calculation of the overall truss, horizontal forces of fixed bearings were analyzed. To realize the structure design of steel truss, reasonable joints design and loading methods were adopted, and effects of horizontal forces on the structure were considered.

Keywords: steel truss; truss pedestal; horizontal force; loading method
