## 1 Introduction
The non-linear modelling of the cyclic behavior of Blockhaus timber log-walls under in-plane lateral loads was investigated. The behavior of Blockhaus log-walls under lateral loads markedly depended on their corner joints. Pinching behavior, strength, and stiffness degradation in joints were properly described [16]. Steel frames with reinforced concrete infill walls (SRCWs) were an interesting seismic-resistant structural solution. The seismic behavior of SRCWs had been the object of many theoretical and experimental studies. Hybrid steel and concrete systems made by SRCWs due to their many advantages as seismic-resistant systems [17; 18], i.e., high initial stiffness beneficial in reducing building damage under low-intensity earthquakes, effective damping characteristics, and potentially easy repairs after moderate damage through the use of epoxy resins on the cracked wall. In order to investigate the behavior of partially-restrained steel frame with RC infill wall (PSRCW), two specimens with one-third scale, one-bay, and two-story were performed under a reversed cyclic lateral load. Test results showed that PSRCW with solid infill walls exhibited moderate ductility capacity and energy dissipation due to the degradation of post-peak strength. PSRCW with concealed vertical slits exhibited much larger ductility, deformability, and energy dissipation capacity than the other one [19]. A study was performed to investigate concrete masonry infills bounded by steel frames and then used the resulting data to evaluate the effectiveness of equations, which suggested the current design standards for both Canada and the US for the design of masonry infills [20]. Shaking table tests on steel frames with autoclaved lightweight concrete external walls were studied. The results showed the presence of infill had obvious impact on the stiffness and load-carrying capacity of the combined systems [21]. An innovative CFS wall with infilled lightweight flue gas desulfurization (FGD) gypsum was presented in this paper. Test observations showed that the infilled gypsum behaved as a diagonal bracing along with wall frames to resist shearing forces [22]. Four steel frame with infill walls specimens were tested under horizontal cyclic loadings. Both experimental and analytical results showed that the stiff RC infill wall dominated the lateral resistance and drift capacity of the test specimens, and that, by adding slit-separated features at the edges of infill walls, improved the drift capacity [23]. In-plane seismic behavior of concrete sandwich panel-infilled steel frame (CSP-ISF) was experimentally and numerically investigated. It was found that addition of sandwich panels leads to considerable increase in the lateral stiffness and strength, ductility, energy dissipation capacity, and equivalent viscous damping ratio of the steel frames [24]. The following deficiencies were identified in existing studies. (1) Traditional CFST structures are mainly used for multi-story and high-rise buildings. Few are suitable for low-rise buildings and even fewer are suitable for industrialized construction of low-rise buildings. (2) Currently, the beam and column of a concrete-filled steel-tube framework are usually connected by a structure comprising a reinforcing ring in the outer side and a diaphragm in the inner side. This joint structure requires a complicated construction process, and the prefabrication level is low. (3) Extant studies on sandwich slabs have focused on the mechanical properties and earthquake-resistance performance of the walls, with scant investigation on the earthquake-resistance performance of walls mounted in frameworks. In this study, a prefabricated concrete-filled steel tubular (CFST) framework composite slab structure is proposed to address the issues associated with rural buildings in China and the deficiencies of extant studies. This type of structure is mainly suitable for low-rise rural buildings and is intended to improve earthquake-resistance and energy-saving performance.
