【正文】 ordered goods, she said. Zhao was born in Shanxi province, but she has lived in Chengdu for more than 10 years. My life was like a running race moving from place to place. I also lived in Beijing and Shanghai before, she said. But Chengdu is a place that you never want to leave once settling down. It is now my second hometown, she said. If the environment is further improved, the city will attract more people to visit and live, with the 72hour visafree policy and pelling conditions in transportation, culture, climate and cuisine, he said. Foreigners also gave positive feedback on the policy. A spokesman from Dell Inc said the pany has a global hub of operation in Chengdu, so the threeday visa has an immediate and positive influence on the pany39。s level of internationalization. The policy will also bring direct economic revenue, Li said. Chengdu has many cultural legacies and is also a paradise for panda lovers with the world39。 （提示： Tg=,Ekn1jjjiiim a x21g2m a x FHGHGF,TT,?????????????????????? ） 14 15 16 Visafree policy brings Chengdu biz, tourism boost. Making national headlines several times, Chengdu39。已知各層重力荷載代表值分別為G1=13000kN,G2=11000kN， G3=12021kN；結構基本自振周期 T1=；設計地震分組為第二組， II 類場地；設防烈度為 9 度。試計算該體系的底部剪力。 （提示：yh0yvs aFA ?? ） 39．單質點結構體系如圖示。 （提示：K2K???） 38．某單層廠房柱牛腿頂部作用的豎向力設計值為 500kN，水平拉力設計值為 150kN，豎向力至下柱邊緣的水平距離為 500mm，牛腿與下柱交接處的垂直截面有效高度為 850mm，鋼筋設計強度為 300N/mm2。q已知 Wk=3kN， qlk=， q2k=／ m； A、 B 柱截面形狀和尺寸均相同，試用剪力分配法求 A 柱在圖示荷載作用下的柱底彎矩。試按公式 T1= TT u? 計 算其自振周期。 試用剪力分配法求 B 柱在圖示荷載作用下的柱底彎矩。m a x ?????????????
