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, 2) casting structural concrete, 3) hoisting up the hub on the temporary support, 4) tilting-up the arms and fastening them to the hub and 5) installing the stay cable or rod adjusting the their tension and removing the support under the hub. The preliminary structural analysis suggested that 30m span domes are feasible with conventional concrete materials.
