Based on the strain energy sensitivity of the element as the optimization criterion,the topology optimization method of the concrete deep beam is developed by ANSYS APDL language.The key stress trusses of the structure are optimized by discarding the elements with low strain energy sensitivity and LESS contribution to the load stiffness of the structure.The optimization of structure topology is verified by double hole deep beam.The results show that the topology optimization algorithm can reflect the load path and stress distribution of the structure,and provide a reference for the design of deep beam structure.
