［摘要］六盤水會議中心鋼結(jié)構(gòu)屋蓋采用鋼桁架結(jié)構(gòu)體系。重點探討了結(jié)構(gòu)設(shè)計中的關(guān)鍵問題，如結(jié)構(gòu)體系選型、構(gòu)件優(yōu)化布置、節(jié)點設(shè)計以及樓板舒適度驗算等。通過不同布置方案的分析比較，實現(xiàn)了設(shè)計優(yōu)化。利用ANSYS軟件進行節(jié)點有限元模擬分析，得出節(jié)點設(shè)計的關(guān)鍵部位，并給出加強措施。利用MIDAS Gen軟件分析大跨度屋蓋在步行荷載作用下的加速度響應(yīng)，采用峰值加速度對樓板舒適度進行評價。

Abstract:Steel truss structural system is applied in the roof of Liupanshui Meeting Center. Critical problems in structural design were comprehensively discussed, such as structural system selection, optimized arrangement of components, joint design, and comfort degree check of floor. The design was optimized according to the comparison and analysis among different arrangement plans. Furthermore, ANSYS software was used to conduct finite element simulation analysis on the joints to find the key parts in joint design, and the corresponding strengthening measurements were proposed. In addition, MIDAS Gen software was employed to analyze the acceleration response of the large-span roof under pedestrian-induced loads. The comfort degree of floor was then evaluated based on the peak acceleration.
Keywords:Liupanshui Meeting Center; steel truss； structural system selection； component arrangement； joint analysis； comfort degree； pedestrian-induced excitation
