Digital flexural materials are kits of discrete parts that can be assembled into a lattice structure to produce functionally useful assemblies. Digital flexural materials enable design of materials with many small and inexpensive flexures that combine in a lattice geometry that permits deformation without compromising the strength of the assembly. The number of types of parts in a kit is small compared to the total number of parts. A product constructed from digital flexural materials comprises a set of discrete units that are assembled into the structure according to a lattice geometry, with a majority of the units being reversibly connected to at least two other units in the set according to the lattice geometry, and wherein, in response to loading of the structure, a reversible deformation of at least part of the structure occurs. An automated process may be employed for constructing a product from digital flexural materials.

A rebar structure includes a plurality of column longitudinal bars to be connected to a beam. The yield point or the 0.2% proof stress of at least a portion the column longitudinal bars is larger than the yield point or the 0.2% proof stress of a normal reinforcing bar defined by JIS G 3112.

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 having 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.

A tie shear connector for use with insulating composite panel structures having a first structure layer and second structure layer, comprising an elongated body having an interior cavity passage formed therethrough from at least one end, and at least one aperture configured to enable the flow of a fluidic hardenable material into a portion of the interior cavity passage. The tie shear connector can also comprise at least on placement pin to aid in depth penetration of the tie shear connector.

An anchor for being embedded in concrete for attachment to a fastener to support a load comprises a plug having a main body portion extending upwardly from a base portion, the plug for being attached to a form board prior to pouring of concrete, the plug having an end portion disposed a distance from the form board; and an anchor body attached to the end portion. The plug is separable from the anchor body and removable from the concrete after the concrete is cured, leaving the anchor body embedded in the concrete, the plug providing a void in the concrete after removal to provide an access opening for a threaded portion of a fastener to attach to the anchor body.

The present invention relates to prefabricated shear reinforcement that is built in the interior of a slab around a column, more specifically to prefabricated shear reinforcement that is capable of having a plurality of bottom and top main bars whose one end extending into a column and a spiral stirrup bent continuously to form a plurality of rectangular shapes surrounding the bottom and top main bars, thereby having excellent fabrication, constructability, and space utilization, providing economical advantages, minimizing labors needed on a construction site, and reducing a period of construction.

An anchor includes a body having a first end and a second end; the body having a side wall between the first end and the second end; the body including an axial hole extending from the first end into the body, the axial hole for receiving an end portion of a rod; and the body including a first longitudinal cutout extending into the side wall to create a first opening into a first portion of the axial hole to expose an end portion of the rod to be inserted in the axial hole to be welded to the body.
