Summary:The invention discloses a topological optimization method of a novel steel truss structure. The method comprises the following steps: step 1, determining an optimization domain; step 2, performing entity modeling; 3, modeling by adopting an entity unit or a shell unit; step 4, carrying out grid division; step 5, applying a constraint and a specified load; step 6, comparing analysis results; step 7, setting solver parameters; 8, setting boundaries which do not need to be optimized in optimization; step 9, setting a response constraint; step 10, applying symmetric structure constraint; step 11, setting optimization target parameters; 12, obtaining a truss initial optimization model; step 13, observing the size and morphology of the optimization model; step 14, carrying out post-processing on the optimization model; step 15, repairing the checkerboard entity; 16, solving the model; 17, ending the process, and if optimization fails, performing the 9th step. The invention has the beneficial effects that steel can
