EVALUATION AND STRUCTURAL MODELING OF 200 m3 CIRCULAR TANK SUPPORTED WITH SOFTWARE APPLICATION

Abstract

Permanent constructions in drinking water systems are of primary use in the development of a population. The objective of this work was to perform a non-destructive surface evaluation and structural modeling of the 200 m3 supported tank under conditions in the town of Pomata, Peru. A sclerometer was used to determine the concrete strength of the circular wall and the lower base of the old tank. The structural evaluation of the old tank was carried out by applying the design tables of the Portland Cement Association (PCA) and modeling with reliable structural calculation software; likewise, in the old tank the spectral dynamic analysis was carried out with the design parameters of the Peruvian National Construction Regulations, structural standards E.020, E.030, E.050, E.060 and ACI 350-01, ACI 350-06. The same results were obtained for the annular and bending stresses in a static analysis using the PCA design tables. According to the technical evaluation of the old tank, which has a useful life of more than 20 years of use in the potable water system; a new tank with the same storage capacity and in the same location was proposed; in the static and dynamic spectral analysis the PCA tables and modeling with software were used; achieving similar results in both tanks. It was demonstrated that demolition is necessary.
