The Influence of Wind Direction on the Inelastic Responses of a Base-Isolated Square Section High-Rise Building

Previous studies show that the largest wind-induced response of a square section fixed-base high-rise building occurs when strong wind is blowing perpendicular onto face, and greatest translational likely to occur in crosswind direction. When it comes base-isolated allows isolation system yield under excitation, inelastic shows distinctive non-Gaussian characteristics fluctuating excitation mean drift phenomenon non-zero load. These may lead quite different result determining most unfavorable Thus, influence direction on discussed this study based synchronous pressure measurement. The multi-story superstructure modeled as linear elastic shear building, while represented bilinear hysteresis restoring force model. peak value estimated through moment-based Hermit model from an underlying standard Gaussian process. results blows displacement, both at top level, along-wind direction, which response. With change combined displacement still inclination angle 0°, other directions also very large, worthy concern.
