摘要:The paper describes the development of a numerical model for analysis of beams retrofitted with external unbonded reinforcement. The experimental phase of the investigation is described in a companion paper, which also outlines the advantages of the method. Because external reinf...

摘要:In an earlier study the authors outlined a strengthening technique for reinforced concrete beams using external unbonded reinforcement. It was shown that the technique could provide useful enhancements in load capacity in all but heavily reinforced cross-sections. The technique o...

摘要:Abstract(#br)The paper presents a theoretical model for ultimate moment capacity of simply supported reinforced concrete beams by way of retrofitting external unbonded ordinary reinforcement. The advantage of this strengthening technique developed by the author in late 1990s lies...

摘要:The city of Karachi, Pakistan (pop. 14 M) sits close to a plate boundary and within reach of earthquakes on numerous tectonically active structures surrounding the city. One can draw parallels—geologic as well as demographic—with another megacity for which seismic hazard is ...
