C型鋼價格樓承板本身有良好的延伸性，自重輕，自振周期長，較大變形下能吸收變形能，結構體系的連接多為柔性連接，圍護結構可隨主體結構發生變位，其抗震性能得到了大大提高。自重減輕也會增強其抗震性能，自重減少一半，等同于降低抗震設防烈度一度，地震作用可降低30％—40％J，從而減少了很多有關抗震的構造要求，降低了工程造價。我國面臨水土流失、環境污染等一系列影響可持續發展的問題，環保建筑的提出應運而生，環保建筑之能源利用高、環境好、在保障人們生活的基礎上消耗低，使用周期長等。開遠C型鋼樓(lou)承(cheng)板建筑恰恰在這些方面能夠滿足要(yao)求，與(yu)其他建筑結(jie)構體系相比(bi)，樓(lou)承(cheng)板建筑沒(mei)有空氣污染(ran)和噪音，也不會對森林等資(zi)源(yuan)造成破壞，并且建筑材料可以回收(shou)再利用，減少了固(gu)體垃圾的出現，有利于人與(yu)自(zi)然的協(xie)調發展，代表著(zhu)建筑行業的新水(shui)平。
