In column-beam connections, the base plate is necessary to transmit the effort acting in the column to the reinforced concrete foundation. The dimensions of the base plate (b d ) are given by considering the pressure transmitted to the subjacent concrete, which must resist without rupture. The thickness of the base plate t p is given by considering the pressure transmitted by the concrete. The number of anchor bolts, the space between bolts just as the welding connecting the column to the base plate are other factors which can influence the choice of dimensions of the base plate. [5]. The recent studies, both experimental and numerical, have shown that other parameters like rising and slip could affect the base plate behavior. The rising and slip are generated by the contact between the base and the reinforced concrete foundation.
