Types of testing of building materials. Structure and compositions of materials. The basic properties of building materials (general and specific properties, physical and mechanical). Basic structural building materials (history, definitions, classification). Elements of building (bearing structure, partition walls, envelope and installations). External and internal forces and balancing conditions. Elements of bearing structures – structure system. Connections and supports. Linear structural elements (columns, beams, arches, grids, frames). Surface structural elements (slabs, walls, arches, shells). Facility foundation (shallow and deep foundations). Types and selection of the structural system depending on the material used for construction and building method (massive, skeletal and mixed).Classification of structures according to the method of building and techniques of building monolithic, assembled and assembled-monolithic structures.
