Numerical Study of Progressive Collapse in Intermediate Moment Resisting Reinforced Concrete Frame Due to Column Removal
Progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. Both General Services Administration (GSA) and United States Department of D...
متن کاملA Parametric Study on the Progressive Collapse Potential of Steel Buildings under Truck Collision
In this paper, the initiation and propagation of structural damage in a building due to the truck collision to one of its corner columns were investigated. For this purpose, a three-dimensional 4-story moment resisting steel frame with intermediate ductility was considered. The structure was designed using ETABS software under standard dead, live, and earthquake loads, and then impact loading w...
متن کاملPeriod Formulas for Moment-resisting Frame Buildings
Most seismic codes specify empirical formulas to estimate the fundamental vibration period of buildings. Evaluated first in this paper are the formulas specified in present US codes using the available data on the fundamental period of buildings “measured” from their motions recorded during eight California earthquakes, starting from the 1971 San Fernando earthquake and ending with the 1994 Nor...
متن کاملEffect of Initial Local Failure Type on Steel Braced Frame Buildings against Progressive Collapse
In many studies, the alternative load path method (APM) has been used for progressive collapse analysis. In this method, one or several columns of the building are removed and the building response is investigated. This method ignores the initial local failure cause of building and this can affect the structural response. Investigation of ignoring the initial local failure cause of steel braced...
متن کاملMechanism 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...
