| Abstract | ||
| The present work is established to determine the analysis of the arched composite beam and the studied parameters compared with the straight one. A computer simulation program, using SAP package, was used to predict the elastic state performance for both arched composite beam and straight composite beam. The parameters studied in the analysis using finite element model of the arched composite beam are different spans (30m, 40m and 50m); different percentages of degrees of curvatures (0%,2%,4%,6%) and different spring constant. [3] The performance of the arched composite beam showed that, when the degree of curvature increased to percentage of 6%, the tensile stress decreases to 70%, the compressive stress decrease to 70%, the deflection decrease to 70% and the horizontal reaction decrease with 53% relative to straight beam. Also using springs at end support of stiffness K (Max-horizontal reaction in case of hinged-hinged support / Max-horizontal displacement in case of hinged-roller support) decrease horizontal reaction 40% relative to hinged-hinged support. | ||
