Abstract:
A method for constructing a large, open-span frame structure, comprising the steps of:lifting a first plurality of pre-cast concrete beam members into radially-extending positions and temporarily supporting said pre-cast concrete beam members in said radially-extending positions; lifting a second plurality of pre-cast concrete beam members into circumferentially-extending positions spanning adjacent said pre-cast concrete beam members in said radially-extending positions and temporarily supporting said pre-cast concrete beam members in said circumferentially-extending positions; and, forming rigid node joints between each said pre-cast concrete beam member in said circumferentially-extending position and said pre-cast concrete beam members in radially-extending positions which said pre-cast concrete member in circumferentially-extending position spans, with an included angle between each said pre-cast concrete beam member in said circumferentially-extending position at each said rigid node joint being from 90Â° to 160Â°.
