摘要

The objective of this research paper is to employ the Method of Initial Functions for analyzing the elastic behavior of concrete beams under various loads, comparing its performance with traditional models like the Reissner–Mindlin theory. We aim to assess the accuracy and efficiency of MIF in modelling beam responses to uniformly distributed and sinusoidal loads, each at an intensity of 100 N/mm. Our results show a stress deviation of only 6.94% from traditional theories, with deflections of 1.18 mm for UDL and 0.59 mm for UVL. The study further explores MIF’s precision in dynamic analysis, particularly its superior amplitude responses to triangular and sinusoidal loads, underscoring its potential to enhance structural analysis in engineering applications.
