Fôrmas e escoramentos para edifícios em concreto armado : critérios para dimensionamento e escolha do sistema

Abstract

In this work, a comparative technical analysis is made for the main elements of a building, beams, pillars and slabs, with respect to the design of forms used for their execution, and also demonstrated to the economic importance of forms and structures in relation to the cost of concrete structure. The cost of a form is made up of its raw materials such as plywood and raw wood, the use or not of metal fittings, workmanship for making the forms and for assembling of the forms, structures and locks, according to the execution period of a work. The objective of the study is to present the importance of a structural design designed in order to optimize the constructive system, keeping the architectural design faithful. Aiming to show succinctly, the possible structural typologies in reinforced concrete that will reduce the cost in the use of the formwork system, horizontal and vertical constructions. The motivation for this work is to put into practice the knowledge acquired in the Dimensioning of Structures of Armed Concrete and Steel, and my experience as a service provider in the civil production of structures in reinforced concrete by the company Max Forma Técnicas em Construções and compare the results of the systems used.
