Comparative study between structural systems in prestressed concrete

Resumo

This work presents a theoretical comparison of distinct modeling of a model structure through linear
analysis using the commercial structural analysis and design software, CSiBridge. The selected structure was a
20.0m spar beam. The central idea was to compare its behavior when varying parameters in the models that
characterize the adopted prestressing system. Aspects such as the structural system, the steel class used, which is
a function of the type of reinforcement, the level and type of prestressing system and the geometric design of the
reinforcement, stand out. The response values investigated in all lines of study were displacements, bending
moments and axial and shear stress, aiming to present a complete and critical analysis, pointing out possible
reasons for the perceived differences.
