Study on the Bearing Capacity of Autoclaved Fly Ash Masonry Short Column

摘要

According to the plane cross-section assumption and static equilibrium, the formulas for the bearing capacity of autoclaved fly ash masonry short column (AFAMC) can be deduced. And in the deducing process, we should consider the stress-strain relations of the various masonry materials. In this paper, the experimental values of bearing capacity of the short column are compared with those from the theoretical formulas. The data coincidence will verify the reasonability of the formulas deduced by the author. The experimental values of bearing capacity are also compared with the values calculated under the formula of Code for Design of Masonry Structures (GB50003-2011). It can be found the theoretical values are higher than experimental values. So the compression bearing capacity of AFAMC based on the code is overestimated which leads to insecurity.
