“…Dry mechanical connections were adopted to realize the joints between floor-to-floor, floor-to-beam, wall-to-structure, column (and wall)-to-foundation, and beam-to-column. The results demonstrated that the proposed new beam-to-column connection system was a viable solution for enhancing the response of precast reinforced-concrete (RC) frames subject to seismic load [5]. A novel prestressed precast reinforced concrete beam-to-column joint was presented.…”

A building structure comprising a prefabricated lightweight concrete-filled steel tubular (CFST) framework composite slab structure is proposed. Five full-scale specimens (i.e., one empty framework and four-walled frameworks) were tested under reversed cyclic loading to study their earthquake-resistance performance. Of the four wall specimens, three were walled using composite slabs, one had no openings, one had a window opening, and one had a door opening. One was walled with a concealed steel-truss slab. A comparative study on the strength, stiffness, ductility, hysteresis characteristics, and dissipated energy of the specimens was performed. The working mechanism of the framework and slab was then analyzed. The results show that, if reasonably assembled and connected, the framework and slab work in a well-coordinated manner. The walled framework had greater lateral load-bearing capacity, better energy-dissipation, greater stiffness reduction, and better deformability than an empty framework. The area and type of slab opening had a significant impact on structural performance because a door or window opening contributed to a smaller lateral load-bearing capacity and initial secant stiffness of the structure. However, this had no clear impact on the accumulative dissipated energy of the structure.

This paper presents the results of experimental and numerical study on a proposed exterior semi-precast moment-resisting concrete connection. Steel linkage element connects precast concrete beam to column in two cases of bolted and welded connections. These connections were compared to monolithic connection based on stiffness, strength, energy dissipation capacity and ductility factor. An accurate 3D nonlinear finite element model has been simulated to study the behavior of these connections. A good agreement was observed between numerical results and experimental ones in behavior and damage mode. Although, all samples satisfied all the code criteria, but the trend of failure in bolted and welded connection was observed on the weld and bolts area, at the connection zone between beam and steel linkage. However, in monolithic connection, the yielding was observed in rebars and crushing of concrete at the end of beam. The initial stiffness of bolted and welded connection specimen was less than that of monolithic connection specimen. But, the beam moment capacity factors of these samples were a little more than monolithic sample; so, the ductility factors of them were a little less than that of monolithic sample.

“…cladding panels, dissipative connections, experimental testing, precast structures, seismic design 1 | INTRODUCTION Seismic design criteria for precast frame structures taking into account the role of the connections have been consolidated and further developed over the last two decades based on extensive experimental activities and theoretical studies developed within a series of European research projects. [1][2][3][4][5][6][7][8] However, there is still a lack of information about the behavior of precast buildings for what concerns the interaction of the frame structure with the cladding panels. This has been clearly shown by the inadequate seismic behavior of the cladding panel connections of precast structures and the consequent structural failures occurred under recent seismic events in Southern Europe, including the 2009 L'Aquila earthquake and 2012 Emilia earthquakes in Italy, and the 2011 Lorca earthquake in Spain.…”

The cladding‐structure interaction of precast concrete frame systems under seismic action has not been properly addressed in the past, as shown by several failures occurred under recent earthquakes in Southern Europe, which point out the need of a revision of the current design practice and technology. Dissipative systems of connections are proposed to this purpose within a general framework for seismic design of precast structures with cladding panels. The proposed connection systems consist of friction‐based or plasticity‐based devices interposed in between adjacent cladding panels or between the panels and the resisting frame to control the level of transferred forces and limit the displacements of the structure. Monotonic and cyclic experimental tests are carried out on both single connection devices and structural sub‐assemblies of two panels. Furthermore, cyclic and pseudo‐dynamic tests on a full‐scale prototype of precast structure with cladding panels are performed. The influence on the structural response of silicone sealant is also investigated through experimental testing. The effectiveness of the tested dissipative connections of the cladding panels in enhancing the seismic performance of precast structures is demonstrated by means of nonlinear dynamic analyses considering the influence of the roof diaphragm action. Design guidelines are finally provided for both single connectors and panel structural assemblies based on equilibrium and capacity design criteria.
