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...

Researchers awarded a considerable attention to progressive collapse analysis in recent years avoid the partial or entire failure of structures. General Service Administration guidelines (GSA) established base deal with such catastrophic failure. For multi-story building, these proposed column removal scenario which one more columns different locations should be removed from structure. Then, re...

Fatigue behavior of glulam moment resisting joint subjected to repeated cyclic loading has not been well clarified. In addition, the accuracy conventional design formulae for rotational stiffness and yield/ultimate should be discussed especially related method obtain material properties. this research, tests were conducted drift pined joints with insert-steel gusset plate tensile-bolted joint. ...
