Dynamic Seismic Analysis and Design of the Clock Tower Structure

The project includes the analysis and structural design, according to the National Building Regulations of a building of 06 levels, the construction of a clock tower located in the district of Huaro—Province of Quispicanchi- Department of Cusco-Peru. The building has the following structural elements: The structure consists of reinforced concrete elements. It is a structure with a system of aporticado in the longitudinal and transversal directions. The roof system consists of columns, reinforced concrete beams, lightened slabs, stairs and masonry partitions. For the seismic analysis a three-dimensional model was elaborated considering all structural elements representing the beams and columns as linear elements (Frame), the lightened slabs as membrane elements (Membrane). Three degrees of freedom were considered at each level of the building (two translational and one rotational). The design spectrum of the seismic standard was used and a dynamic spectral analysis was performed. For the design of the elements, the values obtained in the dynamic analysis were scaled up to values equivalent to 80–90% of the static analysis using the regulatory formula H = ZUCS/R multiplied by the total weight of the building. The required design combinations are established according to the RNE Standard E.060 for reinforced concrete elements, being that the structure complies with symmetry, both in the distribution of masses and in the stiffness, adequate resistance, continuity in the structure, both in plan and in elevation, ductility of the connections, hyperstability and monolithism, lateral stiffness and rigid diaphragm. It is concluded that the design of the structure complies with all the regulatory bases of the RNE and also of the seismic-resistant analysis that is zoned according to its location.
