“…Precast concrete structure has been widely used because of the distinct advantages of high quality, high industrialization level, fast construction speed, low labor intensity, and green construction [1][2][3][4][5][6][7][8]. Over the last decades, many countries and regions, such as the United States, Japan, China, and Europe, have been increasingly advocating the precast concrete structure system for residential and industrial buildings [3,4].…”

“…e connection type not only affects the manufacture and installation process of precast components but also determines the overall structural performance. Great efforts have been made to investigate the mechanical performance of various connection types of precast wall panel structures, such as types of sleeve [1], emulative [5], hybrid [6], bolted [10], grouted [11,15], and friction connection [16,17]. In the previous research, the dry connection presented great advantages for low-rise precast buildings, in terms of quick erection, maintenance, and reuse [18].…”

This paper develops a novel dry connection utilizing high-strength bolts and introduces the corresponding low-rise precast wall panel structure system. To investigate the seismic performance of the structure system with full bolt connections, monotonic loading tests of the connection joint and cyclic lateral loading tests of three full-scaled precast shear walls are both conducted. Based on the test data, axial and shear mechanical models of the connection are given. Meanwhile, experimental results show that the failure mode of the connection is dominated by anchored rebar ductile rupture, and the precast structure system presents a stable energy dissipation capacity and a good seismic ductility. The numerical model of the precast shear wall is then developed and validated by the cyclic loading test. Also a simplified calculation method to predict the lateral strength of the precast shear wall is proposed. According to the calculation results, the distance between the center of the connection and the edge of the shear wall is suggested to be 150 mm, while the wall thickness is recommended to be 120 mm or 150 mm. Finally, a three-story precast wall panel structure is employed to assess the collapse performance of the proposed precast structure system by using the presented numerical model. The results indicate that the proposed structure system with full bolt connections has high stiffness and high seismic resistance against collapse.

In order to promote industrial production of reinforced concrete shear wall, a typical partly precast reinforced concrete shear wall with both end boundary elements castin-situ and the other part precast is experimentally studied. In this paper, three Lshaped specimens of this kind and one completely cast-in-situ specimen as a control group are tested under low-frequency cyclic loading to investigate their safety, applicability, and different characteristics. For the partly precast specimen, the vertical distributed reinforcements of precast part are equivalently spliced by grouting sleeves arranged along the center line of the wall whereas the horizontal reinforcements are directly anchored into the cast-in-situ boundary elements. During the test, the axial compression ratio of these specimens is fixed at 0.2, 0.3, and 0.5, respectively.Such test phenomena and test data including failure modes, yielding load and displacement, the skeleton curve, energy dissipation, stiffness degradation, ductility, and so on are observed, analyzed, and compared. Chinese code and American Concrete Institute code are adopted to estimate the bearing capacity. Results show that the partly precast specimens have good integrity. With the increase of axial compression ratio, the bearing capacity of these partly precast specimens increases whereas the ductility decreases. It is also found that the partly precast specimens have slightly lower bearing capacity compared with the cast-in-situ specimen as well as excellent deformation capacity and ductility, which indicates the tested partly precast shear wall has good and reliable seismic performance and can be used as a structural element in building construction.

“…The horizontal connection between adjacent precast shear wall panels may also be achieved using “wet” methods; for instance, by inserting the extended rebar at the top face of the below panel into the preformed hole at the bottom of the above panel and filling the preformed hole with fresh cementitious grout, or by sleeve‐mortar splicing together with cast‐in‐situ concrete . However, these types of assembling procedures all require some cast‐in‐situ work, which reduces the construction efficiency to some extent.…”

This paper is concerned about the lateral load response and associated working mechanism of a precast reinforced concrete shear wall involving horizontal connections. An assembling method is proposed using dry connection through a horizontal steel connector (H-connector) and high strength bolts. To investigate the effectiveness of such an assembling method, two identical wall-connector assembly specimens have been constructed and tested under monotonic loading and cyclic loading, respectively, while subjected to a constant vertical compression. The test results showed that the performance of the shear wall assembly was generally satisfactory in terms of ensuring the full development of the shear wall strength and ductility. To assist in the interpretation of the experimental results and enable further study on the design approach, a detailed mechanism analysis has been subsequently conducted. The stress in H-connector flange and shear force transferred through each high strength bolt has been deduced on the basis of mechanism analysis. The further sliding analysis within the bolted connections agrees well with the experimental results and therefore confirms the derived formulae for H-connector and high strength bolt.high-strength bolt, horizontal steel connector, precast shear wall, relative sliding, working mechanism 1 | INTRODUCTION Precast reinforced concrete (RC) construction is common in many parts of the world. Typically, it involves the mass production of repetitive and often standardized units, namely columns, beams, floor, and roof elements, and wall panels. Advantages of precast construction include less labor cost and shorter construction time, as well as better quality control. Precast RC structures with special detailing and treatment at the connections are also popular in seismic regions, and lessons are continuously being learned. 1 However, comparing with other precast components, precast RC shear wall is relatively under-developed, and this has become a bottleneck problem in the precast construction of medium to high rise buildings in seismic regions.As it is well known, shear wall is an essential structural member to resist lateral seismic loading in high rise buildings. 2 Due to the need of maintaining high lateral stiffness and resistance, precast RC shear wall poses particular challenges to the assembling techniques. Although there has not been a well-established approach, researchers worldwide have carried out investigations on various kinds of prefabricated RC shear walls. In general, the assembling approaches adopted in these RC shear walls can be classified broadly into two main categories, namely "dry" and "wet" methods.A series of experimental and analytical studies were performed on the unbonded posttensioned (UPT) precast concrete wall system. 3-6 The UPT system is normally Discussion on this paper must be submitted within two months of the print publication. The discussion will then be published in print, along with the authors' closure, if any, approximately nine months after the pr...
