Experimental Study on Collapse-Resistant Behavior of RC Beam-Column Sub-structure considering Catenary Action

摘要：

Under blast or impact loads, disproportionate collapse will be likely to occur for a majority of high-rise building without special collapse-resistant design. This paper presents a collapse-resistant experimental method and test results of five RC beam-column sub-structures with various arrangements of steel bars and various loading velocity. Both ends of the specimens were pin-connected and fixed on steel boxes and two steel tubes were embedded in both ends of the specimen. The load was continuously applied on the top of the middle column in scheduled time by the servo-hydraulic actuator with displacement-controlled mode, and the pin-supported RC beam-column experienced elastic, plastic and catenary stages. The collapse occurred at a vertical displacement of about 400mm due to the
