The textbook outlines the basics of design and calculation of the most simple and widespread load-bearing structures in construction practice. The publication is designed for students and teachers of construction colleges and technical schools, as well as other secondary vocational educational institutions that train specialists in construction specialties, and primarily in the specialty "Construction of buildings and structures" (special. 2902) with all her base-level specializations. It may be of interest to students of higher education, where the discipline "Building structures" is available in the curriculum, but is not profiling.
