Some structural building projects include beams in which can be noticed a relative small ratio between its span and height. These structures are called deep beams and their geometry causes the emergence of nonlinear stresses in the named discontinuity regions. These stresses impose the need to use methods that predict this behavior, in order to provide an appropriate analysis and a safe design. Likewise, the Stringer-Panel Method (SPM) and the Finite Element Method (FEM) prove to be useful. The SPM highlights its simplicity and is based on the determination of the forces through a stringer-panel model of the structure analysed, wherefrom the verification and design can be done. Regarding the Finite Element Method, it was applied using ANSYS software and the linear analysis allowed the accurate visualization of the stresses patterns and their intensity. The present study has the objective to show the procedures of linear analysis of two deep beams through the SPM and FEM, in order to compare the results obtained by means of the two methods and verify the relation between both. Likewise, the softwares SPanCAD and ANSYS have been used, which have provided the stresses in order to accomplish the comparison. Besides, it was pursued to execute the design through de SPM, performing a nonlinear analysis and assuming the verifications and procedures recommended by the NBR 6118:2014 code. The analysis performed using the SPM provided accurate results because there was significant similarity to the stresses obtained using the FEM. Furthermore, the SPanCAD nonlinear analysis allowed the proper design of the reinforcement and the verification of the serviceability limit state. |
