Cross-laminated timber shear wall-concrete core tube hybrid lateral force system

Abstract

The invention relates to an orthogonal plywood shear wall-concrete core tube mixed lateral-load-resistance system. The system includes an orthogonal plywood shear wall, a concrete core tube, replaceable energy-dissipation connectors, a concrete foundation, prestressing swing supports, a first post-tensioned unbonded prestressing bar, a second post-tensioned unbonded prestressing bar, a first steelshim and a second steel shim. The orthogonal plywood shear wall is connected with the concrete core tube through the several replaceable energy-dissipation connectors, the concrete core tube is connected with the concrete foundation through the first steel shim, the second steel shim and the several prestressing swing support, the first post-tensioned unbonded prestressing bar runs through the concrete core tube longitudinally and is fixed by an anchorage device, and the first post-tensioned unbonded prestressing bar runs through the orthogonal plywood shear wall longitudinally and is fixed by an anchorage device and the second post-tensioned unbonded prestressing bar runs through the concrete core tube longitudinally and is fixed by an anchorage device. Compared with the prior art, the system can effectively reduce the damage of orthogonal plywood wallboards and concrete shear walls in an earthquake, energy-dissipation components are easily replaced, and the difficulty and cost of post-earthquake repair can be reduced.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a cross-glued wood shear wall-concrete core tube hybrid anti-lateral force system. Background technique [0002] Earthquakes are sudden, unpredictable, and occur frequently, causing huge losses to human society. my country is one of the countries with frequent land earthquakes, especially the frequent large earthquakes in recent years, which have caused serious earthquake damage to building structures. [0003] Cross-laminated timber is a factory prefabricated engineered wood product in the form of rectangular, straight and flat panels formed by at least three layers of solid wood sawn timber or structural composite panels orthogonally formed by pressing with structural adhesives. Compared with the mechanical properties of traditional wood components, cross-glued wood laminates adopt orthogonal two-way gluing, which can effectively compensate for the large difference in t...
