Trajectory Stress and Angle Values Correlation to Deep Beams Dimensional Ratio

Abstract

SNI 2847-2019 defines a deep beam as a structural component that is loaded on one side and supported on the opposite face, allowing compressive components such as struts to form between the loads and supports. It is also stated that the ratio of the net span of the beam to the height of the beam must match the standards (l/h) 4. The goal of this investigation is to determine the value of the stress’s correlation and the trajectory angle to the ratio of the l/beam h's with a span of 4 meters when subjected to a point load of P = 2,000 kN. In the analysis procedure, SAP v.14 is being used to determine the value of stresses and trajectory angles of variations l/h. The results obtained from this study is ratio of l / h of deep beam affects the magnitude of the stress and the angle of the trajectory. Increasingly the width of the beam has no significant effect on the resulting trajectory angle.
