The topic of this thesis is a collection of objects of the postharvest line in the village Horní Moštěnice by the town Přerov. The thesis resolves the time schedule along with the financial plan. In the drawing of the constructional plant is being solved the establishment of the whole construction. Further is it the technical report, site engineering study and a noise study. The thesis is focused on the storage bins, for which is being developed a detailed time schedule, a budget, a drawing of the machine configuration, a technological standard for the assembly of the storage bins, the principles for the construction management, technical management of the constructional plant, control and test plan, safety and health at work protection and the construction site noise.

La presente tesis tiene como objetivo analizar y evaluar la efectividad de reforzar con acero estructural a una edificación existente que no cumple el control de derivas. La edificación a reforzar, ubicada en el distrito de Lince en la ciudad de Lima, cuenta con un área de terreno total de 193m2, con 5 pisos destinados al uso de oficinas y un sistema estructural de pórticos de concreto armado construido en el año 2004. Se exponen todos los sistemas de reforzamiento con acero estructural más utilizados en la actualidad para rigidizar la edificación y que la estructura logre un comportamiento sismorresistente adecuado. El material del reforzamiento será acero estructural ASTM A36. Se verificará las irregularidades que presenta la edificación existente; dado a que la edificación fue construida bajo las especificaciones de la Norma E.030 del 2004, se actualizarán todos los parámetros sísmicos a la más reciente Norma E.030 Diseño Sismorresistente 2018. Se modela la edificación con cada tipo de reforzamiento con acero, se realiza un análisis símico para comprobar que la estructura cumpla con los requisitos especificados en la Norma E.030, y verificar que los desplazamientos laterales relativos de entrepisos (derivas) no superen el límite máximo permitido de 0.007 establecido en la Norma. De esta manera, se optará por el sistema de reforzamiento con acero más efectivo y viable para la edificación. Por último, se verifican todos los elementos estructurales de concreto y se diseña los nuevos elementos de acero implementados a la estructura, bajo la Especificación AISC 360 para acero estructural. / The objective of this thesis is to analyze and evaluate the effectiveness of reinforcing an existing building with structural steel that does not comply with drift control. The building to be reinforced is located in the Lince district in the city of Lima, has a total land area of 193m2. The building consists of 5 floors for office use, it is a structural system of reinforced concrete porches and was built in 2004. All the systems of reinforcement with structural steel most used today are exposed to stiffen the building and that the structure achieves an adequate earthquake-resistant behavior. The reinforcement material will be ASTM A36 structural steel. Irregularities in the existing building will be verified; Since the building was built under the specifications of Standard E.030 of 2004, all seismic parameters will be updated to the most recent Standard E.030 Seismic-resistant Design 2018. The building is modeled with each type of steel reinforcement, a simian analysis is carried out to verify that the structure complies with the requirements specified in Standard E.030, and to verify that the relative lateral displacements of the floors (drifts) do not exceed the limit. maximum allowed of 0.007 established in the Standard. In this way, the most effective and viable steel reinforcement system for the building will be chosen. Finally, all the concrete structural elements are verified and the new steel elements implemented to the structure are designed, under the AISC 360 Specification for structural steel. / Tesis

Purpose: The purpose of this study has been to investigate the essentials of being able to incorporate high-strength steels (460 MPa and beyond) for structural elements in buildings. As of late, structural steels with a yield point of 355 MPa have been considered standard and have been for the past decade. One of the problems that occur with an increased yield point, is that deflection of structural elements increases, as the Young’s modulus does not increase with increasing yield point. Welding, stability, behavior during fire, and fatigue are also subjects of interest. Method: The study was conducted through several courses of action: a literature review covering the latest research of high-strength steels within the sought-after area of interest, followed by calculations of a truss resting on two columns, being subject to bending moment and compressive force, in both 355 MPa and 700 MPa, in order to review the differences that occur and how they can be counteracted. Lastly, interviews were carried out, where structural engineers gave their thoughts and experiences on the matter at hand. Results: The results show that welding is one of the largest hurdles with being able to utilize high-strength structural steels, though there are newer, more promising methods of welding which can be used, such as electron beam welding. Regarding structural integrity and buckling of structural elements, high-strength steel can be used for trusses, where the structural members are mainly being pulled, opposed to being subject to compressive force. This was shown with the performed calculations, during the interviews, and by the literature overview. Conclusions: The general conclusions of the study is that for welding, further research, education, and training is required for all concerned parts, such as the structural engineers and the on-site welders, which will increase the knowledge regarding how welding of high-strength steels should be performed, but also raise awareness about newer and more modern methods. Fire behavior for high-strength steels are a higher risk factor that should be treated and executed with higher degrees of caution by engineers. Reduction factors for fire affected steel construction elements should be corrected to fit the behavior for high-strength steels as well, as they differ from the current Eurocode 3 for lower class steels. Problems with instability can be counteracted by utilizing the steel in pulled structural members, such as trusses and struts. Lastly, for high-strength steels to be used more widely, structural engineers and manufacturers need to work together for any of the two to profit, as low production rates are costly.
