Mechanism of Collapse of Tall Steel Moment Frame Buildings Under Earthquake Excitation
We expound on the nature of collapse of one class of tall buildings (steel moment frame buildings) under earthquake excitation. Using a parametric analysis of a couple of index buildings subjected to idealized ground motion histories, we establish the ground motion features that cause collapse in these structures. Systematically mapping damage localization patterns, we track the evolution of th...
متن کاملSensitivity of the Earthquake Response of Tall Steel Moment Frame Buildings to Ground Motion Features
The seismic response of two tall steel moment frame buildings and their variants is explored through parametric nonlinear analysis using idealized sawtooth-like ground velocity waveforms, with a characteristic period (T ), amplitude (peak ground velocity, PGV ), and duration (number of cycles, N ). Collapse-level response is induced only by long-period, moderate to large PGV ground excitation. ...
متن کاملprogressive collapse evaluation of rc symmetric and asymmetric mid-rise and tall buildings under earthquake loads
plan irregularity causes local damages being concentrated in the irregular buildings. progressive collapse is also the collapse of a large portion or whole building due to the local damages in the structure. the effect of irregularity on the progressive collapse potential of the buildings is investigated in this study. this is carried out by progressive collapse evaluation of the asymmetric mid...
متن کاملA Retrofitting Framework for Pre-Northridge Steel Moment-Frame Buildings
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...
متن کاملThe Effect of Local Damage on Energy Absorption of Steel Frame Buildings During Earthquake
Progressive collapse is a kind of failure in which whole or large part of a structure collapse when a local damage occurs and distributes to other parts. Many researchers focus on the column removal analysis and study of the structure behavior under effect of gravity loads, so these investigations are mostly carried out on the tall building. Earthquake inspections indicate structural element ca...
