Abstract
Abstract In one embodiment, the concrete post-tensioned multiple dome and integral beam roof modules, utilizing cable-tendons as they are assembled into a roof, form the roof of a concrete water reservoir. A comparative minimum amount of materials are used in this embodiment which is designed to be substantially completely surrounded by earth. The earth fill above is of sufficient depth for the creation of scenic and recreational park facilities, and other multiple uses and also the soil depths in many locations will support tree growth. In this reservoir embodiment, of the overall roof modules, the concrete water reservoir has a continuous floor, inclusive of footings, surrounding side walls, selectively spaced interior shear walls perpendicular to the side walls, spaced columns, either pre cast or formed in place, posttensioned valley beams integrally made in modules with integral domes and supported on the spaced columns, horizontal cable tendons used in the post-tensioning of the overall arrangement of the integral valley beam and dome modules, and expansion, cushion, and sealing materials to accommodate expansion and contraction of the concrete reservoir during temperature changes and surrounding earth movements. Each dome consists of four alike integral roof portions, each one curved throughout on a radius first determined in a geometric plane perpendicular to its respective post-tensioned valley beam at the center of the beam, resulting in single rather than compound curvature construction.

Claim 3
Dependent Claim
93 words
An enclosed concrete water reservoir, as claimed in claim 1, wherein the bottom of the selectively spaced interior shear walls are sloped to rest on sloped portion of the reservoir bottom which extend upwardly from around the level reservoir bottom portions to the bases of the reservoir side walls and are secured thereto to withstand the resultant force of the possible horizontal earthquake loads and the existing vertical dead weight loads of the overhead modules of post-tensioned valley beams and integral domes and the loads of other possible weights carried by these modules.
Claim 4
Dependent Claim
59 words
An enclosed concrete water reservoir, as claimed in claim 2, wherein slight spacing between the shear key structures is selectively filled in some places with elastomer shock pads, so horizontal earthquake loads occurring in only one selected direction will be transmitted to the shear walls and surrounding sloping portions of the reservoir bottom along one side of the reservoir.
Claim 5
Dependent Claim
61 words
An enclosed concrete water reservoir, as claimed in claim 2, wherein some of the spaced columns ae made shorter to carry loads immediately adjacent the inside termination of the interior shear walls and between the overhead integral roof modules and sloping portions of the reservoir bottom below, and these shorter columns at their top and bottom portions have pocket bearing assemblies.
Claim 6
Dependent Claim
