Spillway, SAP2000, Stress Distribution Graph, Acting LoadsAbstract
The stress distribution varies between different areas. This is caused by several main factors such as spillway height and the magnitude of the forces. The research objective is to analyze stress distribution on the spillway structure due to the acting forces and to generate graphs that can be used as a quick way to obtain its structural stress values. The method employs 12 models of ogee-crested spillways with varying heights. The loads acting include hydrostatic pressure, mud, uplift, and self-weight. Stress distribution is calculated using SAP2000 software. The stress results are illustrated against spillway height. Trendlines and polynomial equations are fitted to the graphs and tested with interpolation and extrapolation. Graph validation is performed against previous studies, showing reasonably good accuracy. In conclusion, stress distribution on the spillway structure due to hydrostatic pressure, mud, uplift, and self-weight varies in each area. This study successfully obtains graphs that can be used as a quick method to obtain its structural stress values.
