Abstract:In this paper, 12 laminated reinforced concrete shear walls are designed for cyclic loading tests. Seismic performance of laminated reinforced concrete shear walls with vertical seams are evaluated by the failure mode, deformability, hysteresis curve, stiffness degradation, and energy dissipation capacity. In addition, two different construction measures and construction techniques are designed to study their influence on the wall behavior, which provides a reference for the construction of laminated reinforced concrete shear walls. The numerical simulation of the specimen is carried out with ABAQUS, which is in good agreement with the experimental results. These results provide a technical basis for the design, application, and construction of the laminated reinforced concrete shear wall structure.

“…The shaking-table tests performed on the full-scale 3-storey building evidenced that the prototype building was able to sustain increasing levels of peak ground acceleration (PGA) up to 1.2 g without visible damages (Ricci et al, 2013;Palermo et al, 2014). More in detail, the results of the tests showed that:…”

The use of "ductile seismic frames," whose proper seismic behavior largely depends upon construction details and specific design rules, may do not always lead to effective seismic resistant structures, as dramatically denounced by the famous Chinese artist Ai Weiwei in his artwork Straight. The artwork (96 t of undulating metal bars that were salvaged from schools destroyed by the 2008 Sichuan, China earthquake, where over 5,000 students were killed) is a clear denounce against the corruption yielding to shoddy construction methods. The issue of safe constructions against natural hazards appears even more important in developing countries where, in most cases, building structures are realized by non-expert workers, or even by simple "people from the street," who does not have any technical knowledge on construction techniques and seismic engineering. In this paper, a brief history from the first frame structures to the more efficient wall-based structures is provided within Earthquake Engineering perspectives. The superior structural properties of box-type wall structures with respect to conventional frame structures envisage a change of paradigm from actual "ductility-based" Earthquake Engineering (centered on frame structures) toward 100% safe buildings through a "strength-based" design exploiting the use of box-type wall-based structures.

“…eir applications have been limited by the internal structural defects in the fabrication and difficulties associated with filling of abnormally shaped composite parts. Recently, the fabrication of composite structures using metal hollow spheres [3,4] and aluminum foam elements with APM [5][6][7][8][9][10][11][12][13][14] has become a hot topic of research. e APM element is an aluminum foam sphere with a closed-pore structure of 2-15 mm diameter and a complete nearlyspherical surface, which can be prepared by the modified powder-compacting foaming (PCF) method [2,5,6].…”
