ADHESION OF COMPONENTS OF COMPOSITE STEEL AND CONCRETE CROSS SECTION IN ANALYSIS OF BEAMS WITH CONCRETE ENCASED SECTIONS
Journal Title: International Journal for Computational Civil and Structural Engineering - Year 2019, Vol 15, Issue 2
Abstract
A brief overview of the issues of aggregate work of components of the composite steel and concrete section is made. It is presented various options for the layout of the cross-section of beams used in the practice of design. A review of the design of the regulatory documents regarding the issues of adhesion of cross-section elements is performed. The characteristic of experimental models is given. The features of destruction of models are shown. The reasons of the destruction are analyzed. The case of the loss of the bearing capacity of the element due to relaxation (loss) of adhesion at the steel - concrete interaction boundary is considered. Various shear surfaces of the concrete section are given. Calculations of the bearing capacity of the composite steel - concrete beams for each computational surface were performed, the obtained results were evaluated. Conclusions have been made on the question of ensuring aggregate work in case of composite steel - concrete beams with a fully encased steel core.
