<B>análisis teórico experimental del comportamiento a flexión de vigas de hormigón armado mediante traslapes ineficientes de forma escalonada</b>

Abstract

The purpose of this work is to develop a theoretical-experimental analysis through normative and laboratory tests where the behavior of reinforced concrete beams with staggered overlaps is studied, starting from a base beam with predetermined type geometry, which is tested with a simply supported shape placed at a point load in the center of the beam that determines its deformation. The work is to compare the bending stresses by overlapping where 3 types of beams were made, one beam was made without overlapping and the other two have an overlapping configuration of 0.13 m and 0.08 m, with the following dimensions of the beam are 0.75 m long, 0.145 m high and 0.07 m wide, where the element was designed so that the bending stress affects the steel. Laboratory tests have allowed us to verify that the strength of the tested beams is higher than that proposed by analytical models. It has been found that the resistance up to the cracking point proposed analytically is lower than the one obtained experimentally.
