The paper presents the results of a comprehensive study on evaluation effectiveness retrofit strategy existing steel buildings against progressive collapse. In this respect, it investigates performance and design solution to increase robustness Moment Resisting Frame buildings. A truss system added at building's rooftop level (i.e., ‘roof-truss’), intended define an alternative load path, was i...

The Klandasan Parking Building (GPK) is an 8-story parking built in Balikpapan that serves as vehicle and uses a conventional structure system (columns, beams, plates) where the highest beam about 800 mm. To maximize clearance of each story, alternative planned by removing beams called flat slabs. new plan conducted modifying into dual which consists Intermediate Moment Resisting Frame, plate w...

This work represents an effort to develop one plausible realization of the effects of the scenario event on tall steel moment-frame buildings. We have used the simulated ground motions with three-dimensional nonlinear finite element models of three buildings in the 20-story class to simulate structural responses at 784 analysis sites spaced at approximately 4 km throughout the San Fernando Vall...

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...

Seismic vulnerability of reinforced concrete (RC) buildings is strongly influenced by beam-column joints. Horizontal and vertical structural members converge in joints, as extremely delimited areas where the internal forces core reinforcing bars have elevated stress gradients. In order to fully understand seismic behavior RC related failures T- X-shaped joints (external corner internal-position...
