Numerical Study of Seismic Performance of Reinforced Concrete Moment-Resisting Frame with Cold-Joint

In this paper, the seismic performance of reinforced concrete moment-resisting frame with cold-joint subjected to monotonic lateral load has been studied numerically using Pushover analysis. Two modes fracture may occur for in a in-plane loading. The are Mode-I (stress orthogonal local plane crack surface) and Mode-II parallel surface but front). order model verify its behavior mode I II mechanics, first three-point bending beam an initial notch middle span then S-shaped specimen, used push-off test, have modeled validated. Furthermore, single-story single-span bare monotonically at validated by laboratory results. Then added analyzed. Moreover, investigate effect number spans, considered analyzed two three spans both monolithic (MJ) (CJ) statuses. performance, parameters such as ultimate capacity, stiffness, ductility evaluated. results study show that general, presence little on capacity stiffness significant impact frame.
