A wall either wholly or partially made from a shear-resisting assembly that has a shear transfer device, or plate, disposed between the bottom strut and the underlying foundation. The shear transfer device joins the two anchor bolts, eliminating intermediate foundation bolts by transferring lateral shear loads to the anchor bolts in combination with the bottom strut

Wide-body connectors are provided for concrete sandwich walls. Each connector includes a body with longitudinally thickened portions defining flanges and a thinner inner connecting web extending between the flanges. The flanges provide increased bending stiffness for the connector, while the web provides enhanced shear transfer between the concrete layers of the wall. Anchoring surfaces are formed into or overmolded onto the body to anchor the ends of the connector in the concrete layers of the wall and assist in the creation of end moments ofr the transfer of forces between the concrete layers. Preferably, a lip is provided on the connector to limit the penetration of the connector through the insulation layer of the wall. The connectors transfer forces between the concrete layers, without thermal bridging, such that the wall has a substantially composite character.

The invention discloses a design and calculation method for a reinforced concrete combined part of a mixed girder bridge and relates to the field of bridge design of the mixed girder bridge. The method comprises the steps that the partial prestress of the reinforced concrete combined part is set; a typical force transferring unit is selected as an analyzing designing object; the axial force of the reinforced concrete combined part is computed; according to the thickness and the prestress of a steel plate connected with a bearing plate, the thickness of the bearing plate is designed in advance; whether the thickness of the bearing plate is qualified is checked; when the bearing shearing transferring type reinforced concrete combined part needs to be added, the inner force transferred through a shear key of the bearing shearing transferring type reinforced concrete combined part is initially set to be 30% of the axial force of the typical force transferring unit; the shear key is arranged on a steel structure extending section according to a computing formula; and whether the shear key is qualified is checked according to the formula. The proper reinforced concrete combined part can be designed according to the computing formula, test cost is of no need, the test cycle is avoided, application is convenient, and promotion and application of the mixed girder bridge in city bridges can be well achieved.

Plywood shear panel diaphragms are utilized in building walls and roofs to support against lateral forces such as earthquakes, wind, tornadoes, and hurricanes. Plywood is typically used for the shear diaphragm in wood construction, nailed vertical or horizontal to wood members. When introducing an opening in a plywood shear panel diaphragm, the diaphragm becomes weakened. Shear transfer process is required to maintain integrity in the shear diaphragm at the opening. The strength from the diaphragm is transferred to the openings edges, the top and bottom edges, using blocks between the framing members acting in compression, and the strap, which acts in tension, transfers the support of the diaphragm to opening. When compared to conventional means, the Block Strap apparatus is a better, more accurate, predictable, cost cutting, labor reducing product for providing for shear transfer requirements in typical common wood construction.

The invention discloses a multi-disaster defense structure comprising prefabricated frame columns, prefabricated frame beams, energy consumption angle steel connectors, shear transferring plates and multi-disaster defense steel tie bars, wherein the energy consumption angle steel connectors, the shear transferring plates and the multi-disaster defense steel tie bars are used for connecting the prefabricated frame columns and the prefabricated frame beams. The multi-disaster defense steel tie bars are matched with the energy consumption angle steel connectors to achieve self-resetting and energy consumption of the structure under an earthquake. The shear transferring plates are matched with the multi-disaster defense steel tie bars to meet the requirements of continuous collapse preventing bearing capacity and large deformation of the frame structure. Therefore, destruction of the prefabricated structure when the earthquake and continuous collapse occur can be effectively reduced, a prefabricated frame can conduct self-resetting under the effect of the earthquake and be repaired only by replacing the energy consumption angle steel connectors, anti-seismic and anti-continuous-collapse performance and repairable ability of the prefabricated structure are greatly improved, and the multi-disaster defense structure has important significance for reducing the loss brought by disasters.

The present application relates a core member for a core-stiffened structural assembly. The core member includes a plurality of cell members oriented a direction to provide a tailored stiffness in a certain direction. The core member can further include one or more planar members that can aid in shear transfer between cell members. The cell members can be made from bonding a plurality of corrugated layers together. The core-stiffened structure can be a rotor blade for an aircraft. In such an embodiment, the torsional stiffness of the rotor blade can be tailored in at least one of the chordwise and spanwise directions to provide tailor a torsional stiffness at any give location in the rotor blade.

Provided are systems and methods for producing, packaging and dispensing cooked chunky food that may be a low acid, high water activity food having high organoleptic (e.g., flavor, texture, aroma, color, etc.), and nutritive (vitamins, nutrients, etc.) quality, and an extended refrigerated shelf-life relative to prior art refrigerated prepared foods. Example methods combine hot-filling (e.g., into microwavable self-venting hand-held pouches) immediately after cooking using low-shear transfer at suitable transfer temperature and rate through a fill/dispensing portion sized to provide for substantially unimpeded flow without textural degradation of the chunky food, followed by immediate post-fill chilling and storage under refrigerated and/or frozen conditions. Also provided are chunky foods produced by the methods, and packaging containers (e.g., microwavable self-venting hand-held pouches) suitable for easy, mess-free directed dispensing of the packaged chunky food composition from the pouch by hand, including by children, or adults.
