Wind Resistance Design of Variable Cross-section Towering Structure Satisfying Man's Comfortable Demand

本文提出了变截面高耸结构满足人舒适要求的抗风设计方法,解决了新高耸结构设计规范中已提出但没解决的问题。文中,建立了一般高耸结构顺风向短周期风振加速度最大值的计算公式和园截高耸结构横风向共振加速度最大值的计算公式。并根据试验所得人体感觉舒适度的控制界限,得到了变截面高耸结构满足人舒适要求的二维抗风设计公式。工程实例的计算结果表明,本文方法是简明和实用的。

Wind resistant design method of variable cross-section towering structures satisfying man's comfortable demands has been proposed in this paper and of which was un-solvcd in new towering structure design code. This paper has founded the calculation formulas of maximum value on wind vibrational acceleration of shorter period in following wind direction for general towering structures and resonance acceleration in cross wind direction for towering structures with circular cross-section. According to the control limit of the comfortability of man's feeling gained by the test two-dimensional wind resistant design formula satisfying man's comfortable demand for variable cross-section towering structures have been obtained. The calculation results for the engineering example shows that the method in this paper is concise and practical
