冷弯薄壁结构在地震高烈度地区的应用

Application of Cold-formed Thin Wall Structure in High Seismic Intensity Area

凉山州位于四川省西南部,属于地震多发区,当地基础设施较为落后。为加快推进凉山州基础教育发展,改变学前教育落后现状,凉山州计划建设上百所乡镇中心幼儿园。项目有着明显的时间短、任务重、点多面广的特点。为确保项目顺利开展,在顺应国家大力推广装配式建筑的基础上,采用冷弯薄壁体系结构,能有效地解决当地基础设施条件落后所带来的诸多问题,又能满足当地高烈度地区抗震设防要求,可为同类工程开展应用提供参考借鉴。

Liangshan Prefecture, located in the southwest of Sichuan Province, is an earthquake-prone area, with poor infrastructures. In order to facilitate the development of basic education and change the backward situation of preschool education, the government plans to build hundreds of kindergartens in the central towns. The project has obvious characteristics of short duration, heavy task and other difficulties. To ensure the smoothness of the project and on the basis of conforming to the state's vigorous promotion of prefabricated construction, the cold-formed thin wall structure was adopted, which could effectively solve problems caused by the poor local infrastructure conditions, and could also meet the requirements of seismic fortification in high intensity areas and provide reference for similar projects as well.
