Abstract M oment R esisting (MR) einforced C oncrete (RC) frame system presented in the current seismic design standards and required to on-site action develops soft storey mechanisms. In practice, idealized theorized ductile response specified for this structural type does not occur. these conditions, research study presents a logical scheme regarding development method of MR RC system. The ma...

This paper presents quantitative information on the effectiveness of seismic retrofit solutions using bilinear oil dampers for seismically deficient existing tall steel buildings. For this purpose, a benchmark 40-story space moment-resisting frame building is studied that represents 1970s design practice in North America. Rigorous performance assessment based ASCE 41 recommendations reveals hig...

In the last two decades, high-rise timber buildings have been built using glulam truss system, even with limited openings. Moment-resisting frames (MRTF) semi-rigid beam-to-column connections can be an architecture-friendly way to provide a load-carrying system vertical and horizontal loads for buildings. these structures, of adequate ductility are crucial ensure robustness energy dissipation. ...

This paper is concerned with the determination of optimal sensor locations for structural modal identification in a strap-braced cold formed steel frame based on an improved genetic algorithm (IGA). Six different optimal sensor placement performance indices have been taken as the fitness functions two based on modal assurance criterion (MAC), two based on maximization of the determinant of a Fi...

This work applies 64,765 simulated seismic ground motions to four models each of 6or 20-story, steel special moment-resisting frame buildings. We consider two vector intensity measures and categorize the building response as “collapsed,” “unrepairable,” or “repairable.” We then propose regression models to predict the building responses from the intensity measures. The best models for “collapse...
