    Currently, due to the growing development of the construction sector in society and the consequences of this demand in the environmental sector, it is necessary to resort to new construction systems in which nature is protected and, at the same time, population demands are met without increasing additional costs. It is known that pervious concrete has low resistance due to the volume of voids it contains, consequently it was proposed to reinforce the pervious concrete with polypropylene fibers to increase the resistance to compression with different percentages of application, and later find the dosage related to the requirements of a concrete applied to pedestrian crossings. As a result, the product dosages of the implemented methods obtained 156 specimens, tested at 7, 14, 21 and 28 days of age, which achieved a maximum result against the compression test of 152.34 kg/cm2 which contains a reinforcement. of 0.075 percent polypropylene fiber, it should be noted that the minimum resistance required was 180 kg/cm2, categorizing pervious concrete as deficient compared to conventional concrete.

    Análisis comparativo estructural y económico de una cubierta desarrollada con estructura metálica y estructura de bambú para “un área de uso recreacional” en la hostería Flor de Canela

    The need for a place to live and the environmental crisis are current problems that must be controlled and mitigated in the construction sector, in the present research work a comparative structural and economic analysis of a roof projected with two structural materials was carried out. A widely used material, steel and a material that is gaining market in recent years for its great potential for reforestation and uses in construction such as bamboo. In the research, an analysis of the configuration and the optimal structural system for the roof was made, then a structural analysis was carried out using the static and linear dynamic methods complying with the regulatory controls of the Ecuadorian construction standard to guarantee a safe structure with a resistant earthquake behavior. Finally, the work was concluded with a comparison of the structural and economic response of the two roofs. This work seeks to provide a low-impact construction alternative with the environment and will serve for future engineers to mitigate the environmental problems we currently have.
