Abstract: Nonlinear time-history analyses are conducted on a flat-plate building to explore the damaging effects of vertical ground acceleration on punching shear failure of slab–column connections, which have been exposed by field ...

Abstract: Using a macromodeling approach and alternate path method, dynamic and static analyses are performed to assess the progressive collapse resistance of a multistory reinforced concrete flat-plate building lacking structural ...

Abstract: Several catastrophic progressive collapses of RC buildings, initiated by column failures, occurred in the past under sustained gravity loads long after the initial construction. To study the near-failure behavior of aged ...

Abstract: Beam compressive arch action (CAA) is an appealing mechanism for reinforced concrete (RC) frames to resist progressive collapse after losing a column during an abnormal event. Past studies have focused predominantly on the ...

Abstract: A macromodel for slab-column connections is created for use in the system-level progressive collapse analyses of reinforced concrete flat-plate structures. The proposed model jointly uses shell and connector elements to ...

Abstract: This paper documents the findings from a dynamic collapse experiment carried out on a single-story two-by-two bay reinforced concrete flat-plate substructure. The test specimen had a 0.4 scale, represented older flat-plate ...

Abstract: Experiments and finite element (FE) simulations were conducted on corrugated double-skin composite (Co-DSC) walls consisting of concrete-filled steel tubes (CFTs) and corrugated steel faceplates connected by tie bolts with ...

Abstract: Reinforced concrete beams tend to elongate after flexural cracking and yielding; however, the elongation is restrained by the surrounding structural components in a RC moment frame. Experiments were conducted on seven ...
