Abstract

RESUMEN La concepción estructural del sistema prefabricado Gran Panel Soviético, le confiere un alto grado de hiperestaticidad. Sin embargo, existen incertidumbres acerca del comportamiento sísmico de las edificaciones construidas con este sistema en la provincia Santiago de Cuba, por la presencia de daños patológicos en los elementos y juntas, así como por las modificaciones en el peso y la rigidez que han realizado los moradores. Dada la incidencia de los factores del suelo en el acrecentamiento de esta problemática se valora el comportamiento sísmico de estos edificios en relación al tipo de suelo, la resonancia y la susceptibilidad del deslizamiento, con la consecuente probabilidad del vuelco. Se recurre primeramente a un análisis documental de la zona de emplazamiento, y en una segunda etapa, se realiza la modelación estructural de dos variantes de un edificio, a través del software ETABSv18. Se concluye que, en ambas variantes no es posible el deslizamiento, pero concurre la posibilidad del vuelco. Igualmente, es poco probable la resonancia y la licuefacción del suelo.

ABSTRACT The structural conception of Soviet Large Concrete Panel Housing System gives it a high degree of hyperstaticity. However, there are uncertainties about the seismic behavior of buildings built in Santiago de Cuba province, Cuba due to the presence of pathological damages in joints, elements, and also due to the modifications in weight and rigidity made by inhabitants. Given the incidence of soil factors that increase the problem, the seismic behavior of these buildings is evaluated in relation to the type of soil, resonance and landslide sensibility, with probability of overturning. Firstly, a documentary analysis of location area is used and a structural modeling of two variants of building is carried out in a second stage, by using the ETABSv18 software. It is concluded that, in both variants, landslide is not possible, but it is evident that overturning is really possible to occur. Similarly, resonance and soil liquefaction are unlikely.

Valuation of the Durability of the Concrete Used in the Precast Great Soviet Panel System

Yamila-Concepción Socarrás-Cordoví, Liliana González-Díaz, Eduardo Rafael Álvarez-Deulofeu … (2020)

Abstract The durability of the concrete of the precast Great Soviet Panel system is valued through the resistance to compression, ultrasonic pulse velocity, surface methods, humidity and potential of corrosion. The evaluation is approached, essentially, through experimental and statistical methods, nevertheless, historical-logical and technical methods, such as surveys and interviews, are used in order to gather a bigger amount of information on the resistance to compression of the elements in the original project. While analyzing the results, we can conclude that, in elements in a good technical-constructive state that conform the constructions in exploitation, concrete has an average resistance. However, in elements with the presence of pathological damages, the resistance is low due to the fact that elements show chemical deterioration processes caused by water exposure, which generates the formation of soluble paste compounds, loss of mass, and decrease in mechanical resistance, among other alterations. At the same time, carbonation of concrete is triggered, which, in turn, causes the corrosion of the reinforcing steel. This corrosion leads to the cracking of concrete, delamination of steel, decrease of the concrete-steel adhesion, and other manifestations that affect the durability of concrete. Therefore, the incidence of the durability of concrete should be valued in the structural seismic behavior of constructions.
