Abstract

This paper presents a framework for quantifying coupled dynamic wind load effects on build-ings. The wind loading input for this scheme may be derived either from multiple points synchronous scanning of pressure on building model surfaces or through high-frequency force balance (HFFB) measurements. The analysis takes into account the cross-correlation among wind loads in principle directions and the inter-modal coupling of modal response components with closely spaced frequencies. This study focuses on the modeling of buildings whose mass centers at different floors may not be located on a single vertical axis. The Complete Quadratic Combination (CQC) rule is clearly defined for the analysis of wind load effects under correlated multiple excitations as it differs from conventional uni-component earthquake excitation. A representative tall building with 3-D coupled modes and closely spaced frequencies is utilized to demonstrate the proposed framework and to discuss the coupled building response to wind.
