Review and comparative analysis of computational algorithms for modeling the dynamics of elastically supported structural systems

The paper presents global stability comparative analysis of two distinctive structural systems for one 25 - storey high steel building. These are the system with rigid and the system with hinged joint connections between beams and columns in the steel structure. The analysis focuses on the basic structure which was designed only to carry vertical loads, and on the corresponding structure which was stabilized with vertical bracings in the fa?ade walls. Additionally, the paper shows several intermediate steps in the designing of stabilized systems. Static and dynamic design of the relevant structural systems, as well as the control of stress, deformation and stability under the seismic forces of seismic intensity VIII, was done on a computer, on the 3D computation models using Finite Element Method.

Environmental Demand

The construction sector, by direct or indirect actions, consumes more than 40% of the global energy produced and is responsible for 30% of CO2 emissions. It is a need of the construction industry to transform its practices and processes by proposing systems of lower demand to the environment. In this sense, closed prefabrication and industrialization as a constructive process could be the key to seek savings and efficiency from its origin to the end of life of buildings. In this context, this article presents a methodological proposal of quantitative, qualitative and comparative analysis of the structural systems of eight prototypes presented in the “Solar Decathlon” contest in its North-American and Latin-American editions (both of them in 2015) and the European edition (in 2014). This methodology deduces the characteristics of a structural system of lower environmental demand and the characteristics of these constructive processes, in favor of a new paradigm of sustainability and to be applied in innovative systems of new housing models.
