THE FRAME CONCRETE STRUCTURE

Abstract

This work shows the influence of characteristics of the alternating load and its intensity on state strain deformations of critical sections in frame structures. The development of a methodology for assessing the ultimate bearing capacity and deformability of reinforced concrete frame structures under the action of alternating dynamic loads is presented. Analysis in elastic hyperstatic frame structures corresponds to rather weak stresses not involving crack and non-elastic deformation of concrete and steel. Therefore, for a greater level of stresses, such as the seismic action, the distribution of efforts is totally different from the static study.
