A fatigue resistant gravity based spread footing under heavy multi-axial cyclical loading of a wind tower. The foundation having a central vertical pedestal, a substantially horizontal continuous bottom support slab, a plurality of radial reinforcing ribs extending radially outward from the pedestal. The pedestal, ribs and slab forming a continuous monolithic structure. The foundation may have a three-dimensional network of post-tensioning elements that keep the structural elements under heavy multi-axial post compression with a specific eccentricity intended to reduce stress amplitudes and deflections and allows the foundation to have a desirable combination of high stiffness and superior fatigue resistance. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

Provided are a concrete foundation structure capable of firmly fixing a precast concrete foundation to a ground, and a method for constructing the concrete foundation structure. A concrete foundation structure 10 includes a precast concrete foundation 16 having a projecting portion 30 embedded in a ground G. An anchor plate 20 is placed inside an excavation hole 18 formed in the ground G, and the precast concrete foundation 16 and the anchor plate 20 are connected by a connecting member 22. In the excavation hole 18, a backfill portion 24 is formed of a backfill material 94 including a solidifying material and soil. A filler layer 26 is formed of a filler 96 containing a solidifying material between the precast concrete foundation 16 and the backfill portion 24. The precast concrete foundation 16 has a through-hole 42 through which the connecting member 22 is inserted, and the filler 96 forming the filler layer 26 is filled through the through-hole 42.

The present invention provides a bidirectional energy-transfer system comprising: a thermally and/or electrically conductive concrete, disposed in a structural object; a location of energy supply or demand that is physically isolated from, but in thermodynamic and/or electromagnetic communication with, the thermally and/or electrically conductive concrete; and a means of transferring energy between the structural object and the location of energy supply or demand. The system can be a single node in a neural network. The thermally and/or electrically conductive concrete includes a conductive, shock-absorbing material, such as graphite. Preferred compositions are disclosed for the thermally and/or electrically conductive concrete. The bidirectional energy-transfer system may be present in a solar-energy collection system, a grade beam, an indoor radiant flooring system, a structural wall or ceiling, a bridge, a roadway, a driveway, a parking lot, a commercial aviation runway, a military runway, a grain silo, or pavers, for example.

A building system (5) including a panel system (10) and a formwork system (78). The panel system (10) includes a plurality of modular panels (12) arranged to fit with one another in a predetermined grid arrangement (13) to form side walls of a building in a fitted condition. At least the bottom sides (24) of each of the modular panels (12) includes a plurality of apertures (34) that are arranged at predetermined spaced apart locations along the bottom side (24) so as to coincide with the predetermined grid arrangement (13). The formwork system (78) includes a plurality of modular formwork members (80) that are associated with each of the modular panels (12) to provide a supporting slab (72) having slab apertures (76) to allow coupling with the modular panels (12). Modular panels (12), formwork members (80) and associated methods of use are also disclosed.
