“…This event also exposed many existing problems in the earthquake resistance of rural houses in China. The earthquake resistance of rural houses has become an important subject in China’s national defence and disaster reduction (Ge et al, 2010; Yuan et al, 2019; Zhang and Jin, 2008; Zhao et al, 2009).…”

This paper proposed a ‘self-contained’ structural system for structural columns and ring beams and used recycled concrete blocks (RCBs) as wall materials. Based on this design concept, a full-scale model of a new masonry building structure was established. The Castaic wave, the Taft wave, and an artificial wave were sequentially input to the shaking table, and the effects of different ground motions on the structural model were simulated. The changes in the natural frequency and damping ratio of the test model and the acceleration, displacement, and strain responses of the structure were studied under different seismic wave excitations. Finally, the overall seismic resistance of the model was determined. The results showed that the ‘self-contained’ structure system exhibited excellent cooperative performance. Moreover, the test model can fully meet the degree-7 seismic fortification requirements, in which the damage sustained from small earthquakes is not substantial, the damage sustained from moderate earthquakes can be repaired, and the damage sustained from large earthquakes does not cause structural failure. The results showed that RCBs can replace ordinary concrete blocks in practical engineering projects. However, the construction measures for the door and window openings should be strengthened in actual projects.

“…Graphite is a very stable material under varying sliding cycles and is not affected by humidity. Yuan et al (2019) established numerical isolation models using finite element analysis software ABAQUS, for traditional masonry, sand cushion seismic isolation, and composite isolation. During the dynamic analysis, the composite isolation system was found best among all others because it dissipated maximum seismic energy.…”

Masonry Structures are extensively built in developing countries because of their economy and ease of construction but they are brittle and have poor seismic performance. This paper presents an experimental and numerical study conducted to investigate the optimum thickness of the isolation layer of a newly introduced economical seismic isolation system termed as Reinforced-Cut-Wall. Hollow concrete blocks were used to optimize the properties of the isolation layer during the experimental and numerical study. The performance of the proposed isolation system is evaluated by installing it in a 1:3 reduced scale unconfined brick masonry wall through cyclic loading tests.

Ma et al [10] carried out precracking blast vibration damping tests to investigate the vibration damping effect of the precrack formed; Zhou et al [11,12] explored the future trends of seismic resistance, isolation, passive, and active control technologies; Zhu et al [13] illustrated the scope, advantages, and disadvantages of the use of different seismic isolation bearings and dampers in building structures, as well as the practicality and economy of further improving seismic isolation bearings and damping devices; Zhou [14] illustrated the effectiveness of the laminated seismic-isolated system in controlling seismic response; Yuan et al [15,16] analysed the dynamic response of several seismic isolation structures and traditional masonry structures and concluded that the seismic isolation structure can effectively absorb seismic energy, among which the composite isolation system has the best seismic isolation effect; Wang et al [12,[17][18][19][20] studied the variation of stresses and strains with time in structures subjected to strong dynamic loads such as explosions and impacts. Li et al [21,22] studied the stress-strain relationship of soil under repeated loads to provide data support for practical engineering.…”

A new type of light steel-wood-plastic residential structure in rural has popular in recent years in rural Yunnan, China. The application of light steel, wood, and new plastic materials in practical engineering is gradually increasing due to its advantages of green ecology and waste utilization, and its response characteristics under earthquakes have attracted great attention. In this paper, seismic-resistant models, seismic-isolated models, and seismic-damped models for multistorey light steel-wood-plastic structures were established using the SAP2000 finite element software based on different seismic response methods. The seismic-isolated model is divided into five schemes, namely, LRB400, LRB500, LRB600, high damped, and friction pendulum-isolated bearings, and the seismic-damped model is divided into three schemes, namely, ordinary bracing, soft-steel bracing, and BRB bracing at the same locations around the 2nd floor of the building. Nonlinear time analysis was carried out for the nine schemes, comparing the period, structural interstorey displacement, base shear, top displacement, top acceleration, and economy of the structure under the action of an 8-degree earthquake. Results show that the period of the seismic-isolated system increased by approximately 130% compared to the seismic-resistant system, and the period of the damped system decreased slightly compared to the seismic system, the interstorey displacement, base shear, and top acceleration of both the seismic-isolated system and the damped system were smaller than those of the seismic-resistant system, and the seismic-isolated system decreased by approximately 40% compared to the damped system, and the seismic-isolated system was more effective than the damped system. From the comparison of postearthquake damage cost and full-cycle cost, the economic performance of the seismic-isolated structure is better than that of the damped and seismic-resistant structures. The conclusions of this paper can provide a scientific reference for promoting the use of new light steel-wood-plastic residential buildings.
