Numerical analysis and simulation of reinforced concrete beam deformation
The deformation of concrete structure can lead to severe problems as it undesired state of member at which excessive stresses been formed on the concrete body and reinforcement leading to cracks and weaken the overall structure. The variety of deflection on a concrete beam depends on number of factors including the condition of loading and the physical properties of that beam. Analysis the behavior of deflection and simplifying the way to detect of values can support that designer to figure out the available strength of the member and the actual needing for increasing that strength. The study aimed to put important figure of the deflection of reinforced concrete beams under concentrated load and under uniform distributed load. The magnitude of settlement along the span of the beam was evaluated from low values at the supported to the maximum values for each loading case. The study moves more than that by using the finite element technique to bond the number of segments that calculated from the support to the section when the deflection needed to be detected. The study used the method of double integration and updated it by deriving new formulas for each loading condition. The maximum deflection for each case were determined and explained in tables and figures. The increasing of deflection relating to various lengths of beams were showed in table. The study then used the linear regression technique to build linear formulas for easing the steps to find the degree of deflection. The new formulas were tested by explaining the different between the derived and calculated settlement at the middle of span. The difference was so small indicating the validity to use linear equation that based on the number of segments and the span length as well as the modulus of elasticity and the moment of inertia. The study supported its outline by using finite element analysis under ANSYS program. The results were showed in figures by the programs and satisfied the values that reached.
