Abstract

This is a project that aims make the equivalent grid program, a component of the CALCO system (reinforced concrete designed), capable of being used to make the floors analysis of usual dimensions. Besides make more accurate, while generating finer meshes, it is intended aiding some specific reinforced concrete structures characteristics. Thus, part of this scope is to introduce a connector module type "spring" so that this tool can be used to analyze pre-cast structures with semi-rigid connections. Through the module of the spring supports the program may be used to resolve element foundations on continuous media like a beam based on a elastic foundation or a mat foundation on elastic foundation (Raft) and a pile immersed in an elastic soil, discreting their elements with discrete support closed spaced. The module existing today, the result of stock FAPESP undergraduate research, not yet allows calls these tests. The CALCO system developed by the work group GESC (the group that supervisor belongs) with their graphics inputs and outputs already allows analysis floors quick and simple need, and can provide results output showing the efforts and requesting displacements through graphs. The graphic modules were developed in AutoLISP and have no memory limitation, depending only on the ability of computer used. Thus, this objective is work equip the module resolution structure in this case the grid equivalent, with a large capacity if it need to be using the decomposition of structure into smaller substructures so that it can resolve usual precision reinforced concrete floors. It is also envisaged the use of that allows incremental loading analyze the effect of cracking of reinforced concrete members. It is expected that with the development of this work possible to tell which tool analysis of concrete structures that may in future be linked to other that have been developed within the CALCO same system as, for example, a three dimensional module.
