Abstract
We propose a novel construction method for dome skeleton using Tilt-up concrete and Rotational Erection System (RES). The construction procedures are 1) setting the edge form and rebar on the level floor pad, 2) casting structural concrete, 3) hoisting up the hub on the temporary support, 4) tilting-up the arms and fastening them to the hub. We studied the two types of structural configuration with a) intersecting arms and b) dual layer arms. The preliminary structural analysis suggested that the 30m span domes are feasible with conventional concrete materials.
