Abstract:
By accomplishing tests of some RC beams, the deformation processes and destruction modes of those glued-steel RC beams under loading tests werecarried out. The effects of amount of glued-steel, positions andareas of steel plates on the bearing behavior of the RC beams, such as short periodrigidity, deflection, cracked load, ultimate load and destruction modeswere discussed. Through compared the theoretical results with the tested ones,it was found that the reduction coefficients of bearing capacity of glued-steelRC beams were mainly varied with the relative depth of compression zone. Theformulations of calculating reduction coefficients, bearing capacity of bendingand deflections were put forward. The designing suggestions and technique measures to decide the suitable width-to-thickness ratios, positions and areas of glued-steel RC beams were also presented. All these can be acted as the good reference for designing and determining bearing capacity of the RC beams strengthened by bonded steel plates.
