Moment resisting frames as one of the conventional lateral load resisting systems in buildings suffer from some limitations including code limitations on minimum span-to-depth ratio to ensure the formation of plastic hinges with adequate length at beam ends. According to seismic codes, in ordinary steel moment resisting frames the minimum span-to-depth ratios should be limited to 5 and in speci...

Wind and earthquake disasters in the world often cause billions of dollars of damage to buildings, most of which is to non-engineered buildings-especially homes. Wood-frame homes use connectors which exhibit partial rotational rigidity at the member ends, making analytical solutions difficult. This is due to the lack of information about the complex behavior of the connections used in this type...

This paper focuses on investigating the structural behavior of members and connections that are part moment frames under combined effect bending thermally induced axial force during a compartment-fire event. The finite-element analysis method was employed to conduct this study using models benchmarked against experimental data from several past studies while utilizing temperature-dependent mate...

A case study of retrofitting a 20-story pre-Northridge steel moment-frame building is presented. Twelve retrofit 4 schemes are developed with varying degrees of intervention. Three retrofitting techniques are considered: up5 grading the brittle beam-to-column moment resisting connections, and implementing either conventional or 6 buckling-restrained brace elements within the existing moment-fra...

A new method for seismic design of structures with the aim controlling earthquake damage to a prescribed level is presented in this paper. The specified special moment frame buildings vertical and horizontal regularity. main idea determining story drift correlation selected index value. For purpose, Park-Ang correlated maximum drift. Through performing several nonlinear dynamic analyses steel r...
