モルタル目地厚さが異なる組積プリズムの圧縮挙動を予測するFEモデルの開発

Abstract

A finite element model was developed to study the effect of mortar bed thickness in the compressive behavior of masonry prisms. For this, microplane models, calibrated using 10 mm mortar bed prisms, were used to predict the behavior of prisms with 30 mm and 60 mm mortar beds. The results showed the model could replicate the behavior of the experimental data generally. The models whose components differed significantly in compressive strength were affected by a variation of mortar thickness. In them, a reduction of the confinement effect of brick units over mortar beds was observed when mortar bed thickness increased.
