The purpose of this study is to analyze the foundation beam linked between two shear walls in the presence of lateral loads. Mat foundation with shear walls is one of the most commonly used reinforced concrete structural systems to resist the lateral load. When two independent walls are connected with a link beam, also known as the coupling beam, the overturning resistance of the building is largely increased. However, the coupling beams are relatively weaker structures and can develop larger stresses. When there is a mat foundation, or pile cap in case of pile foundation, the part of the foundation which is right below the coupling beam where no shear wall is present, will also get large stresses due to the highly rigid nature of adjacent shear walls. Most of the lateral deformations are imposed only on the coupling beams and foundation beam. There is not much literature or design procedure found in books and codes to mitigate the high risks associated with the foundation beam between shear walls on its design vulnerability. This thesis is focused on the risks associated with exceptionally high forces on the foundation beam due to earthquake forces.

The main work of the diploma thesis is a draft and a static judgement of chosen horizontal and vertical parts of prefab hall with a crane runway. The chosen parts are the girder, the column, the bracing, the foundation beam, and the foundation pad. The model for gathering of intern forces is made by the program SCIA Engineer 18.1 with the use of a bar 3D model of the whole project. The parts were judged on the ultimate limit state. The prestressed girder was judged on the ultimate limit state and the serviceability limit state.

The aim of the diploma thesis is to design particular vertical and horizontal elements of the prefabricated gym hall. The supporting structure of the gym is formed by means of the column system with the use of the roof preloaded trusses. The entrance part of the building is designed as a column system using load-bearing beams and prefabricated ceiling sections. Overall, the structure of the building consists of columns, footings, foundation beams, reinforcing beams, prefabricated components which function as a ceiling structure, components functioning as a grandstand, a load - bearing beams a preloaded roof trusses V1. The diploma thesis designs particular supporting elements of the construction together with the construction of a grandstand.
