## 1 Introduction  
When studying the force-bearing performance of low buildings in villages and small towns, researchers have attained fruitful results, which can be roughly categorized into three schools [1; 2; 3; 4; 5]. Developed countries, such as the United States and Japan, take the lead in the first category, as they have developed a well-designed standard system for seismic resistance. Related tasks--the issuance of compulsory regulations, the release of earthquake insurance and tax collection--fall under the jurisdiction of each country directly. Some European countries have drawn on the seismic research at hand and have carried out the analysis of structural resistance against progressive collapse and the standard of design. Some Latin American countries, such as Peru and Costa Rica, make up the second school. Constantly plagued by earthquakes, these countries have put anti-seismic tasks at the top of their agenda. In line with the local culture, the geological environment on the ground and the economic reality, they have worked actively to study seismic technology; simultaneously, they encourage people to improve the seismic performance of their houses by leveraging government subsides, e.g., a host of enhancement technology research programs for adobes have been carried out to theoretically underpin the work of seismic safety in rural areas. Countries of the third school, located in Asia and Africa, though constantly plagued by earthquakes, have yet to grow the economic muscle to carry out large-scale disaster prevention efforts. In India, for example, 70% of its buildings have poor seismic resistance. Although the government unveiled a public policy of disaster alleviation-working to improve quake-proof capacity via supportive measures in the 1990s, the campaign turned out to be a disappointment due to poor management. Considering the economic difficulties of countries like Nepal, the international community has lent a helping hand, and the recipient countries have encouraged researchers to enhance the seismic performance of local residences; however, the outcomes largely stay at the theoretical level. Some North African countries, such as Algeria and Morocco, have yet to register visible progress in the nationwide application of seismic enhancement measures, though the relevant works have been included in the government agenda. By and large, most of the developing countries--due to economic difficulties--have yet to launch a regulatory and managerial yardstick for rural housing, which explains the limited progress in seismic technology and the poor seismic resistance of most rural buildings. Without technological backup, these countries will be trapped in a vicious cycle in the long run. In response to the climbing temperature worldwide, all countries have committed to boosting the development of their low-carbon industries in their own way. Under such background, the architecture field works to contribute its due share in this all-out endeavor. With this vision of low carbon and environmental protection, the world has experienced a transition from the traditional clay-brick masonry structure to a newly developed masonry design, the mechanical performance of which has become the R & D focus of researchers in this field. [PERSON] and his team studied the influence of the height-width ratio on the shear strength of a concrete-block wall. The results indicated that strong structural columns evidently help to improve the shear stress of the wall [6]. [PERSON], on the other hand, worked with his team to experimentally study 32 pieces of a reinforced block wall, exploring the influence of different loading approaches on the bearing performance of the overall wall structure. Their findings showed that the increase in compressive strain in the vertical direction drives up the shear stress of the wall while simultaneously bringing down the deformative capacity of the structure [7].
