A digital technical document on the calculation of a reinforced concrete continuous beam using an analytical approach and the finite element method (FEM). The file is a full-fledged engineering study that can be used as a template for structural engineers or an example for students and teachers.
This document is an excellent tool for those who want to master modern methods of calculating reinforced concrete structures with regard to real loading conditions and physical and mechanical properties of materials. It will be useful for both a student studying material resistance or design of reinforced concrete structures and a practicing engineer looking for a reliable, transparent, and flexible solution for performing calculations. The editing and automation capabilities make it easy to integrate into your documentation system or methodology.
The model geometry is based on matrices. To change the number of beam spans or the number of segments in each span, simply edit the corresponding input vector.
Example: change a 3-span beam to a 5-span beam: [6 9 6] → [6 6 9 6 6].
The program will perform all further calculations automatically: generate node coordinates for beam discretization, set boundary conditions, connect nodes with rod finite elements, etc.
Special attention in the document is paid to working with loads.
Two types of loads are considered: permanent (dead load) and temporary (live load). Each of these loads is applied to each segment of the beam. A load case is introduced into the model that operates with two coefficients for the dead load (greater than and less than one) and two coefficients for the live load (greater than and equal to zero). The zero value models the situation when there is no load in the span. The program automatically searches through all possible load combinations and displays the final extreme value of the shear force, bending moment, and deflection to the user.
