The number of modes should be selected according to the participant coefficient of mode when calculating the internal force by the response spectrum method ; ( 4 ) the roof plate of large base which connect the towers together should be thick enough but not exceeding the proper scope that the towers and the large base can vibrate together, ( 5 ) in structures with large base and muti - towers, with increasing of the capacity of the large base, the inter - story shear force will increase while the inter - story displacement will decrease as to fulfill the ductility request to avoid the large base becoming weak story, but meanwhile, the upper story will turn into weak story, thus the coefficient r s should be within 2. 0 ~ 3. 0
採用振型分解反應譜法計算結構內力時應根據振型參與系數選擇振型避免漏選；大底盤多
塔樓結構連接各
塔樓的裙房屋面剛度應做得大些，以保證底部裙房與上部
塔樓共同振動，但也不能過剛；大底盤多
塔樓結構底盤承載力的加強將使底盤層剪力增大、層間變形減小，但易於滿足延性要求，在一定程度上可避免底盤成為薄弱層。但底部加強會導致薄弱層的上移，因此採取提高底盤承載力的
措施的效果是有限度的，承載力系數s宜取為2 . 0 3 . 0之間。
The recovery of atmospheric light oil yield of atmospheric in the northern atmospheric distillation tower of shenghua teaching & test factory, science and technology group of china university of petroleum has been increase by about 4 or 5 percent through the following methods : changing the tray perforation of atmospheric tower, adjusting the amount of stripping steam and the outlet temperature of the atmospheric heater and merging atmospheric excess vapor into 3rd atmospheric drawn - stream to keep the fractions content of bottom oil below 5 % before 350
