在改革开放搞活经济的大潮中,沈阳地区许多临街居住建筑把窗改成门,作为商店、饭店、旅馆、发廊等门市用房。这种改动,将会对建筑物原有结构的承载能力,尤其是对建筑物的纵向抗震能力,有很大影响;如果不加合理的控制,一旦地震来临,将会给国家和人民生命财产造成损失;而一概限制,又会阻碍第三产业的发展,抑制社会经济发展的活力。 In the tide of reform and opening up and invigorating the economy, many street-facing residential buildings in Shenyang have changed their windows into doors and used them as stores, restaurants, hotels, hair salons and other retail outlets. This change will have a great influence on the carrying capacity of the original structure of the building, especially on the vertical seismic resistance of the building; if it is not controlled properly, once the earthquake arrives, it will give life and property to the country and people. It causes losses; while restricting it, it will hinder the development of the tertiary industry and inhibit the vitality of social and economic development.
