- ÍtemAcceso AbiertoAnálisis de las propiedades físicos- mecánicas de la mampostería con perforación horizontal sometido a altas temperaturas(Universidad Católica de Cuenca., 2024) Acosta Chilpe, Jefferson Mauricio; Cordero Cabrera, Carlos Julio; 0106700107; García Calle, Anthony AlxanderCurrently, horizontal perforated masonry is one of the most widely used materials in construction due to its strength and durability. However, there is a lack of knowledge about how this material behaves under different thermal conditions. Therefore, analyzing the physical-mechanical properties of horizontal perforated masonry subjected to high temperatures at different exposure times is crucial to assessing structural behavior. To start this research, horizontal perforated bricks, and mortars, beams, and brick panels were made to expose them to high temperatures for different times (5, 10, and 15 minutes), using a blowtorch, domestic gas, and a refractory oven. Compression strength tests reported that the masonry panel exposed to 15 minutes of fire lost 9% of strength compared to the base panel. The brick exposed for 15 minutes decreased by 37% in compression strength. The mortar exposed for 15 minutes showed a 58% reduction. The trio model lost 26% of tangential bond strength compared to the standard model. The gas emission test indicated that the average CO levels in five samples were 561 PPM. Heat transmission at higher temperatures resulted in a minor temperature difference in the indirect part not exposed to fire. Beams decreased their flexural strength by 69.5% compared to the standard model.
