| Abstract [eng] |
Master’s thesis ‘Strength evaluation of three-hinged arch’ is relevant, since majority of public, industrial and agricultural purpose buildings or private houses are designed with glued wood elements instead of using reinforced concrete or metal elements. Research object of the final thesis is the Public Library of Druskininkai municipality, since the building is designed by using glued wood arch constructional elements. The aim of Master’s thesis is to evaluate the strength of constructional element (half arch) of the Public Library of Druskininkai municipality and to assess possible solutions to increase the strength indicator. Final thesis describes the purpose and usability of three-hinged arch, constructional analysis of Public Library as a separate building and methodology of arch strength. After analytical research the followings tasks were carried out: analyzed possible solutions of how to evenly spread the tension according to the length of constructional element (half arch), defined impact of thickness and modulus of elasticity of constructional elements towards the rigidity and strength of beam, evaluated and selected appropriate measurements of reinforcements in order to have more even spread of tension, calculated bearing capacity of reinforced constructional element. The final thesis consists of 6 parts: introduction, explanatory (theoretical) part, methodology, exploratory (analysis) part, conclusion and references. |
