Numerical‐experimental analysis of a braced steel frame subjected to fire following earthquake

Evaluation of 2D concentrically braced frames with cylindrical dampers subjected to near-field earthquake ground motions

Near field earthquakes have imposed major damage to buildings in the past years. In some cases, the intensity of such damage is too considerable to be disregarded. The most effective way to improve seismic performance of buildings is applying a seismic control technique. The cylindrical friction damper is one of these methods, which has become popular for its desirable performance in the energy...

Reliability Analysis of Steel Building Frame Under Earthquake Forces

A simplified fragility analysis of steel building frame is presented which can be used for preliminary estimate of its probability of failure. The risk analysis procedure uses the format of probabilistic Risk Analysis (PRA) and considers band limited white noise at the bed rock as the seismic input. The steel building frame is modeled as a 2D frame and Pushover analysis is then carried out to o...

OPTIMUM PERFORMANCE-BASED DESIGN OF CONCENTRICALLY BRACED STEEL FRAMES SUBJECTED TO NEAR-FAULT GROUND MOTION EXCITATIONS

This paper presents a practical methodology for optimization of concentrically braced steel frames subjected to forward directivity near-fault ground motions, based on the concept of uniform deformation theory. This is performed by gradually shifting inefficient material from strong parts of the structure to the weak areas until a state of uniform deformation is achieved. In this regard, to ove...
