Abstract: Monte Carlo simulation is used to quantify the reliability of reinforced concrete cantilever beams without stirrups designed using ASCE 7-98 load factors with strength reduction factors given in Appendix C of ACI 318-99 ...

Abstract: Typical rehabilitation procedures for posttensioned slab bridges involve removing concrete from the top surface of the bridge, replacing corroded reinforcement, and resurfacing with new concrete. These permanently change ...

Abstract: Conventional design and evaluation procedures usually classify steel through-truss bridges as single-load-path structures; however, their historic performance has demonstrated considerable structural resiliency. This paper ...

Abstract: A mechanical model for unbonded seven-wire tendons with broken wires that accounts for the effects of interwire friction and contact forces between the tendon and surrounding concrete is derived. The model is an essential ...

Abstract: This paper presents the derivation and experimental validation of a mechanical model for unbonded seven-wire prestressing tendons with a single broken outer wire. The model has practical significance because corrosion of ...

Abstract: Testing of buildings and their components to failure under realistic wind loading is difficult under controlled conditions and presents a significant limitation in optimizing building performance. On one hand, the temporal ...

Abstract: Reclamation of biologically treated wastewaters is frequently enhanced with the use of constructed wetlands and wastewater lagoons that remove nutrients and persistent organic pollutants. To better design systems utilizing ...
