ABSTRACT
The building’s plan dimensions are 36 x 36 meters with an 18 x 18-meter gravity core at the center and typical story heights of 3.9 meters. The SEI/ASCE Minimum Design Loads for Buildings and Other Structures is used to establish the wind load. The structures are assumed to be in Chicago and within category III, which implies that there is a substantial hazard to human life in the event of failure. Based on the code, the basic wind speed is 40.2 meters per second (90 mile per hour). One percent damping is assumed for the calculation of the gust effect factor.
