Abstract Numerous reinforced concrete structures require strengthening due to mistakes in detail engineering design, incorrect execution during construction, or overloading. One method of structural is use haunch beam casted near column. The development infrastructure Indonesia leads an increase cement use. This phenomenon causes a greenhouse effect higher CO 2 emissions, so that effort perform...

In this study, the behavior characteristics of I beam-to-concrete filled tube (CFT) column connection is studied through experiment and finite element models under the monotonic loading. To validate the finite element modeling, at first, an experimental model is made and experimented. After validation of the finite element modeling, different models were created in the software. The studied par...

an energy based damage index based on a new nonlinear finite element (fe) approach applicable to rc structures subjected to cyclic, earthquake or monotonic loading is proposed. the proposed method is based on the evaluation of nonlinear local degradation of materials and taking into account of the pseudo-plastic hinge produced in the critical sections of the structure. a computer program is dev...
