Wind-Induced Response Control Model for High-Rise Buildings Based on Resizing Method

Abstract

A variety of methods have been applied to reduce the effect of the wind-induced vibration of a high-rise building as the excessive wind-induced vibration at the top of a high-rise building can cause physical and psychological discomfort to the user or the residents. For structural engineers, the most effective approach to control the wind-induced responses of high-rise buildings would be to control the stiffness or natural frequency of the building. This paper presents a practical design model to control the wind-induced responses of a high-rise building. In the model, the stiffness of a high-rise building is maximized to increase the natural frequency of the building by the resizing algorithm. The proposed design model is applied to control the wind-induced vibration of an actual 37-storey building during the initial stage of its structural design.

Experimental and Analytical Investigation Based on 1/2 Scale Model for a Cleanroom Unit Module Consisting of Steel Section and Reinforced Concrete

“…Therefore, scale models are usually manufactured for experiments. Existing studies using scale models mostly focused on the evaluation of seismic performance or wind performance of structures [18][19][20][21][22][23], and experimental studies to evaluate the microvibration performance of high tech facility structures have rarely been reported.…”
