Masonry Dome Behavior under Gravity Loads Based on the Support Condition by Considering Variable Curves and Thicknesses

It is necessary to recognize masonry domes’ behavior under gravity loads in order strengthen, restore, and conserve them. The neutral hoop plays a crucial role identifying the dome’s distinguish between its tensile compressive regions. When it comes determining position dome with same brick material, addition curve thickness, support condition located on boundary line significant parameter that has received less attention past. Therefore, this research aims comprehensively define behaviors based condition’s effect behavior, thickness parameters, by hoop(s). method graphical numerical analysis sign-changing positioning first principal stress (hoop stress), shell theory extracted from finite element (FEM) Karamba3D of macro-model. case studies are four types supports: fixed, free X- Y-axes, all axes (domes placed drum), pendentive drum). For each condition, twelve curves varied thicknesses for considered. Results variables show that, general, domes can be identified: single-masonry no hoop; double-masonry where hoops single treble-masonry double hoops.
