Effectiveness and strength of autoclaved aerated concrete (AAC)‎ in the composite section R. C. beams and slabs

Abstract EN

An ideal situation for material saving in structural design is to reduce the structure's weight without compromising its strength and serviceability.

the objective of this study is to use autoclaved aerated concrete (AAC) for the composite section.

the reinforced concrete section in AAC blocks is used as infill material.

this research aims to develop the composite section, a reinforced concrete sandwich with a filling of autoclaved aerated concrete blocks used in beams and slabs.

the present study was conducted to investigate the structural behavior of beam and slab infill AAC.

a finite element model based on the computer program (ANSYS workbench 20 r1) has been developed to predict the behavior and strength of lightweight composite section reinforced concrete element beams and slabs.

this study contains two parts, the first part presented seven models of beams, and the second part presented five models of slabs.

the results show that the difference between that solid beam and beam infill AAC at failure load is 12.7%.

this study aims to reduce weight without compromising the composite section's resistance and efficiency.
