## 1 Introduction
Another purpose is to secure the short and long-term stability of mid- to low-rise buildings by obtaining convenient construction, stiffness against deformation, and ductility for efficient energy absorption [8; 9]. In relation to this, an objective of this study is to investigate the seismic performance of double-row reinforced ceramsite concrete sandwich wall panels. The feasibility of upgrading a new wall panel from a non-load-bearing partition wall to a load-bearing seismic wall has been examined by conducting cyclic load tests on five wall panel specimens [10]. Other researchers have presented experimental and mechanical studies on the flexural behaviors of fiber-reinforced polymer (FRP) fabric-reinforced ultra-high-performance concrete (UHPC) panels. Glass FRP (GFRP) and carbon FRP (CFRP) fabrics were investigated [11]. In addition, researchers have investigated the behavior of reinforced concrete beams strengthened in flexure using externally bonded CFRP rod panels (CRPs) fabricated using 4-mm rods spaced at 9.5 mm. The experimental program consisted of a control beam and three beams strengthened with either a continuous CRF, a spliced CRP with two half-length CRPs spliced through a 150 mm finger joint, or a spliced and end anchored CRP [12]. In other research, a method of connecting precast concrete walls with GFRP composite sheets was investigated. The method can be used either as a seismic retrofit of existing welded steel plate connections or in new construction [13]. Additionally, an experimental study of the improvement of the tensile and flexural strength of CC panels through the employment of external reinforcement by an FRP sheet was presented in which the tensile and flexural behaviors of CC and FRP-reinforced CC panels were investigated through uniaxial tensile and four-point bending tests in both warp and weft directions [14]. Another study investigated the impact and post-impact behavior of steel-concrete composite (SC) panels. Impact tests were carried out on eight specimens in an instrumented drop hammer rig [15]. In addition, three kinds of GFRP connector, including a flat plate, a corrugated plate, and a hexagonal tube connector, were investigated for potential use in precast concrete sandwich panels (PCSPs) [16]. Other experiments investigated the blast-resistant characteristics of hybrid fiber-reinforced concrete (HFRC) panels by contact detonation tests. Control specimens of plain concrete, polypropylene (PP), polyvinyl alcohol (PVA), and steel fiber-reinforced concrete were prepared and tested for characterization in contrast with PP-Steel HFRC and PVA-Steel HFRC. The fiber-hybrid effect index was introduced to evaluate the hybrid effect on the explosion-resistance performance of HFRC panels. It revealed that neither PP-fiber nor PVA-fiber provide a positive hybrid effect on blast-resistant improvement of HFRC panels [17]. A disadvantage of previous research is that increasing the strength of the damaged structure requires reinforcement of the structural members and a lengthening of the con struction period. However, based on this study, it is possible to recover the damaged part of the structure by making a concrete panel and prevent secondary cascading collapse. Although there have been many studies on concrete reinforcement using reinforcing bars and mesh, there have been few studies using carbon grid fibers instead of tension members. In addition, this study shows that it is possible to increase the flexural strength by using the carbon fiber grid, which is effective in suppressing cracking activity. Ultimately, this study aims to develop concrete composite panels with carbon fiber grids for emergency earthquake damage recovery and reinforcement.
