“…It is known that the level of the wind-induced vibration of a high-rise building with a natural frequency range of 0.1~1.0 Hz can be assumed to be inversely proportional to the natural frequency of the building (Tallin, Ellingwood 1984;Griffis 1993). Tallin and Ellingwood (1984), Chan and Chui (2006), and Chan et al (2009) have proven that the wind-induced response can be reduced by increasing the natural frequency of a building.…”

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.

“…Chan and Chui (2006), Chan et al (2009Chan et al ( , 2010 proposed optimal design methods to minimize the structural weight or cost while satisfying the serviceability condition using cross sections of members as a design variable. They used the Optimality Criteria (OC) as an optimization tool.…”

“…The ESL approach has also been incorporated into the development of a dynamic response optimisation technique in order to improve the computational efficiency during dynamic optimisation process (Choi & Park, 2002;Kang, Choi, & Park, 2001). Recently, an integrated wind-induced load analysis and stiffness optimisation method has been developed for serviceability design of tall buildings while allowing for instantaneous prediction and updating of equivalent static wind loads during the design synthesis process (Chan & Chui, 2006;Chan, Huang, & Kwok, 2009).…”

Wind-resistant design of tall buildings has been traditionally treated using the equivalent static load approach. In order to account for the uncertainties in random wind excitation, it is necessary to develop a comprehensive and reliable dynamic optimisation technique in the time domain. The optimal lateral stiffness design problem of wind-excited tall buildings consists of (1) identifying the critical dynamic drift response in the time domain and (2) searching for the optimal distribution of element stiffness of the building subject to multiple drift design constraints. The critical time-history drift constraints of a wind-excited building are first treated by the worst-case formulation and then explicitly expressed in terms of element sizing variables using the principle of virtual work. The extreme value distribution and the Gaussian assumption are employed to formulate and simplify the probabilistic drift constraints, which are explicitly considered in the dynamic optimisation problem. The system reliability associated with the interstory drift is estimated approximately by the bound approach to ensure that the most cost-efficient solution also attains an acceptable reliability level. A full-scale 45-story building example under wind tunnel derived time history wind loading is presented to illustrate the effectiveness and practicality of the reliability-based dynamic optimisation technique.

“…Most optimization studies conducted so far on 3D steel frames are performed using beam element discretizations [5][6][7][8][9]. However many phenomena, like local buckling, non-conventional geometries, structural elements with web openings, among others, that may affect significantly the behavior of the structure, cannot be taken into account with the beam element simulation.…”
