“…The research on the prefabricated sandwich insulation wall mainly focuses on the mechanical properties of the concrete slab joints between the inner and outer leaves of the wall under various loads [1][2][3][4][5][6][7][8] and the seismic properties of the wall [9]. The current research results on the performance of connectors have certain reference value for this paper.…”

In recent years, prefabricated buildings have been vigorously promoted and applied widely in China. Precast sandwich core insulation wall is one of the important means to realize building energy saving. This paper studies the pull out properties of a new V-shaped steel truss connector and shear properties. The test results show that: when the anchor depth of the V-shaped steel truss connector is 15mm, 25mm, 35mm respectively, the safety coefficient has reached 9.22, 9.42 and 9.68 respectively. However, the anchorage depth of the inner leaf plate did not increase significantly against the pulling bearing capacity, and brittle failure occurred at the pull rod of the outer leaf plate. The test results show that this kind of wall has high safety factor, and the safety factor even above 9.0, which can fully meet the safety performance requirements of the structure. The research conclusions of this paper can provide reference for relevant theoretical analysis and engineering application.

Structural lightweight concrete is "significant in contemporary construction. This concrete provides technical and environmental benefits, so it is intended for use in the next millennium. Density is frequently more important than strength for lightweight concrete structural applications. A lower density at the same strength level reduces "self-weight", "foundation size," and construction expenses.In addition, using lightweight concrete as opposed to standard weight concrete could provide additional benefits such as heat and sound insulation. A special type of "self-cured lightweight concrete" has been developed to utilize the voids in lightweight aggregate's water reservoirs for curing.The experimental investigation of the structural behavior of lightweight concrete as a function of concrete type and bonding was conducted. Cubes and cylinders were employed in the experimental investigation. Concrete type (normal weight concrete and lightweight concrete) and cement content (350, 400, and 450 kg/m3) were considered as test variables.

“…Therefore, a reduction of nearly 10% in the self-weight of a floor slab may lead to a 5% reduction in the self-weight of an entire building. Many researchers have conducted extensive studies on PCSSPs, but only a few have regarded the use of lightweight materials to reduce the self-weight of building superstructures [3,5,[6][7][8][9].…”

Experimental and analytical studies were conducted to investigate the structural performance of lightweight foam concrete composite sandwich panels (LFCCSP) of total number six as one-way action slab, differing in their thickness and tested under out-of-plane load. The details of the test setup and procedures were demonstrated. The results attained from the experimental tests were analysed and discussed which comprise, compressive and flexural strengths of foam concrete, the influence of aspect ratio (L/b), and observation of cracking patterns. Also, the analytical study of finite element analysis (FEA) using LUSAS software was employed and the degree of composite action of the test LFCCSP panels was also studied in both analytical and experimental studies. Result displays that crack patterns appeared in only one-direction with similar behaviour reported on solid slabs, in particular, at the case when both concrete wythes act as one structural composite unit. Foam concrete (FC) was briefly used to cast LFCCSP panels. The experimental results were compared with the given FEA data, showing a reasonable degree of accuracy. Hence, in the basis of the results obtained, LFCCSP slab can be used as a substitute system element to traditional flooring system.
