摘要

巨型结构风激振动特性非常复杂

其动力性能受多种参数的影响。为合理考虑这些因素的影响

以某48层巨型钢结构为研究对象

针对无控、设置粘滞阻尼器和粘弹性阻尼器三种分析工况

系统研究了其在平均风和脉动风荷载共同作用下的动力响应。通过结构顺风向侧移响应、构件内力响应及顶层加速度响应等一系列数据

揭示了风速攻角、基本风压、附加阻尼比及二阶效应等对此类结构体系风振控制动力性能的影响规律与变化趋势

并依据分析结果对其抗风分析与设计提出了相应的建议

因而具有实用参考价值。

Abstract

Wind-induced vibration characteristics of mega steel structures are very complex.Its dynamic performance can be influenced by all kinds of parameters.In this paper

a mega steel structure of 48 floors is analyzed.Aiming at three analysis cases

i.e.

without dampers

setting viscous dampers and visco-elastic dampers

structure dynamic responses under interaction of mean wind and fluctuating wind are studied comprehensively.By using the series of data gained from alongwind structural displacement response

internal force response of structural component and acceleration response of top-level

the influence law and change trend of dynamic performance of wind induced vibration control for high-rise buildings produced by attack angle of wind velocity and basic wind pressure

additional damping ratios

second order effect and so on

are studied in details.Some suggestions are made for practical structure analysis and design.
