In this project, the main research objective is intend to seek criteria for evaluating the capacity of BAC screw fasteners with mixed configuration of waterproof seal washer, sealer tape and different pre-drill holes to determine shear and tension strength values for the screws used in cold-formed steel connections. The thesis presents the design methods and test program conducted to investigate the behavior and strength of the screw connections in shear and tension test. Test results were compared with AISI design provisions to determine if new design equations will be developed for those screws used in BAC cooling tower applications. LRFD resistance factors and ASD safety factors were investigated to the proposed design equations.

This diploma thesis deals with construction technology project of a newly-built automotive industrial hall on the complex Hauk – Police nad Metují. The aim of the main construction object is to build a double aisle steel hall for industrial purposes including maisonette built-in which will become social and technical facility for prospective workers. The main construction facility is complemented by secondary structures, creating functional complex for required purposes. The thesis is focused on implementation of the main load-bearing prefabricated steel structure and cladding made of selected system. An integral part of the thesis include main technology phases realization study of the main construction object, a technological prescription filled-in with assembly drawings, a design of machine assembly including dealing with its transportation, a site equipment project, time schedules, a budget, a test and inspection plan and a security measures design for selected risks. The thesis is suplemented by a specialized section dealing with the heating of reinforced landscaping.
