Abstract:
A 10-story reinforced concrete building with intermediate moment frames and ordinary structural walls is designed to satisfy the provisions of a set of building codes widely used in the United States and around the world. A two-dimensional (2-D) analytical model representing the nonlinear properties of the structural framing is implemented in computer software. The analytical model is subjected to 104 recorded earthquake ground motions consistent with the “intermediate” seismic environment of the building. The results enable comparison of the expected performance of a codecompliant structure and actual performance as represented by the numerical model. It is concluded that the prescriptive code-based approach can lead to critical underestimation of seismic demands. Of particular concern are the anticipated shear forces, which for some key structural components are beyond the design capacities. Coupled with structural detailing employed in these structures, the results indicate a high potential for relatively brittle failures in some key components during design-level shaking.
