The truss structure has a history spanning thousands of years. Over time, it has evolved from a simple planar geometric structure to today's intricate spatial configuration. Furthermore, its utilization, construction techniques, and material selection have undergone significant advancements. Optimizing the truss structure is particularly crucial in accordance with specific working conditions. Targeted optimization can enhance structural strength, augment aesthetic appeal, reduce project costs, and minimize environmental pollution. Truss structure optimization primarily encompasses size and shape optimization, topology optimization, and material optimization. Size and shape optimization involves determining the optimal dimensions and form of the truss under operational conditions using programs and algorithms. Topology optimization focuses on complex truss structures by employing various algorithms to identify the most efficient components while eliminating inefficient ones. Material optimization entails utilizing new materials that align with engineering requirements as well as environmental sustainability and economic benefits; traditional materials may not necessarily be used entirely or partially for constructing the truss. In the future, with the development of the application of trusses and construction technology, optimizing their structure will become more and more important.
