TL;DR: In this paper, the implication of the development of shear wall plastic hinges in high-rise dual systems has been investigated analytically the seismic response of three code conforming designed buildings with 16, 27 and 45 stories.
Abstract: This paper studies the implication of the development of shear wall plastic hinges in high-rise dual systems. Multi-plastic hinge approach is intended to reduce the effects of higher modes of vibration in tall structural walls under earthquakes. This research investigated analytically the seismic response of three code conforming designed buildings with 16, 27 and 45 stories. These buildings which consist of a core wall/special moment frame dual system are modeled with four different approaches with single, dual, three and four plastic hinges, and some main structural responses including moment and shear distribution and values, drift ratio distribution and values, floor accelerations, contribution of frame in dual system and finally energy dissipation among plastic hinges are assessed. Findings of this research show that the application of multi-plastic hinge approach in wall design can properly affect seismic behavior of core walls and leads to improvement of system seismic capacity and economy of design. The investigation also shows that the application of multi-plastic hinge design concept can cause better use of frame nonlinear deformation capacity which would help better control of effects of higher modes. Based on analyses results, more frame contribution and improvement of wall behavior is observable in models with three and four plastic hinged walls in comparison with single plastic hinge model designed based on ACI 318-14 provisions.

TL;DR: In this article, the thickness of steel plate and the distance between studs are selected as the parameters of the new shear wall structure, and 9 groups of models are used for parametric analysis.
Abstract: At present, China's construction industry is developing rapidly towards the goal of "design standardization and industrial production". The State Council and local governments have also issued relevant documents on the development of fabricated steel structures, the development of assembled steel structure in China has been promoted. The Shear Wall structure is one of the most important components to ensure the earthquake resistance of the whole building, which can obviously improve the overall anti-lateral stiffness of the building, so it is widely used in high-rise buildings. In this paper, the thickness of steel plate and the distance between studs are selected as the parameters of the new shear wall structure, and 9 groups of models are used for parametric analysis. Finally, the data are compared and corresponding conclusions are drawn.

TL;DR: In this article, a cross-shaped plug device for a shear wall is proposed, in which the first mounting boxes and the second mounting boxes are poured in the upper and lower shear walls, respectively, and sliding rods are arranged at the positions, at the first through holes, of the second mounted boxes.
Abstract: The invention belongs to the technical field of fabricating of building components, and particularly relates to a cross-shaped plug device for a shear wall. Aiming at the solving the problem that a fabricated shear wall is connected through a device, and consequently connecting fastening performance of the shear wall cannot be ensured, the following scheme is put forward currently, specifically, the cross-shaped plug device comprises an upper shear wall and a lower shear wall, a plurality of first grooves are formed in the bottom end of the upper shear wall, first mounting boxes are arranged at the position, at the first grooves, of the upper shear wall, clamping plates are fixedly connected to the inner walls of the two sides of the first mounting boxes correspondingly, fixing columns arefixedly connected to the inner walls of the bottom ends of the first mounting boxes, a plurality of second grooves are formed in the top end of the lower shear wall, second mounting boxes are arranged at the position, at the second grooves, of the lower shear wall, first through holes are formed in the bottom ends of the second mounting boxes, and sliding rods are arranged at the positions, at the first through holes, of the second mounting boxes. According to the cross-shaped plug device, the first mounting boxes and the second mounting boxes poured in the upper shear wall and the lower shear wall are fixedly connected, thus the upper shear wall and the lower shear wall can be connected, operation is easy, and stability is good.

TL;DR: In this paper, a 3D printing reinforced masonry shear wall is used to construct masonry shells in order to replace the original concrete small hollow blocks of the original masonry shell.
Abstract: The invention discloses a manufacturing method for masonry shells in a 3D printing reinforced masonry shear wall. The method includes the following steps that a, the first layer of masonry shell is manufactured to the pre-buried elevation position of transverse reinforcements through 3D printing; b, the transverse reinforcements are arranged at the top of the first layer of masonry shell; c, the second layer of masonry shell is manufactured at the top of the first layer of masonry shell through a 3D printing technology, so that the transverse reinforcements are buried in the masonry shells; and d, the steps b and c are repeated to complete manufacturing of the masonry shells. By means of the manufacturing method for the masonry shells in the 3D printing reinforced masonry shear wall, the reinforced masonry shells are integrally formed through the 3D printing technology, original concrete small hollow blocks are replaced, the site construction labor force is greatly reduced, the construction processes are reduced, the building quality is guaranteed, and building industrialization is facilitated.
