冷却塔塔筒内力影响面与风荷载效应分析
Influence Surfaces of Internal Forces and Wind Effects of Hyperbolic Cooling Tower Shell
摘要
Abstract
Studies were focused on the influences of shell load on the shell internal forces of hyperbolic cooling towers,and the influence surfaces of internal forces were employed in the illustration.It was found that the influence surfaces of latitude axial force,latitude moment and meridian moment show the striking local effect,or these internal forces are just influenced by the pressure around their locations.The influence surface of meridian axial force shows the minor local effect,or it would be influenced by the pressure along the shell height.The shear force and torque moment are between the former two conditions.Furthermore,the local effects are more profound in latitude than in meridian direction.Due to the latitude local effect of influence surfaces for all internal forces,the latitude distributions of wind pressure and internal forces show great similarities.关键词
