Analysis of the Structural Characteristics of Rural Residential Buildings in Hainan Province

Most of the rural houses in Hainan Province are self-built by the residents, and due to the constraints of geography, economic conditions, and professional technology, many houses have problems such as poor construction quality, low strength of materials, and no anti-seismic precautions, which result in poor seismic capacity of the houses and make them susceptible to serious damage in case of earthquakes. Through the field survey, there are mainly stone-wood structures, brick-stone mixed structures, brick-wood structures, brick-concrete structures, frame structures and other structural types of houses in Hainan Province, which can be roughly divided into four categories according to the construction age. This paper analyzes the structural characteristics and seismic weaknesses of township houses of different construction ages in Hainan Province, intending to provide theoretical value to the seismic defense and subsequent reinforcement of township houses in Hainan Province. The results show that the houses in the township areas of Hainan Province are mostly masonry structures, and there are a large number of old masonry structures. Among them, the stone-wood structure, brick-stone mixed structure and brick-wood structure are almost not equipped with structural measures, and there is only biting masonry between the transverse wall and the longitudinal wall. The seismic performance of these buildings is relatively poor, and they are vulnerable to damage when they encounter local fortification-intensity earthquakes.
