日本清水建设公司最近研制出一种强度比普通钢筋混凝土柱高10倍的超级混凝土柱,并已进入实用阶段。这种超级混凝土柱的截面比普通钢筋混凝土柱小,因此增加了使用面积,而且还能节省造价5～10%左右。最适用于100层以上的超高层大楼。超级混凝土柱是由普通混凝柱外面包一层圆形 Japan’s Shimizu Construction Co., Ltd. recently developed a super-concrete column that is ten times stronger than ordinary reinforced concrete columns and has entered a practical stage. The super-concrete column has a smaller cross section than ordinary reinforced concrete columns, thus increasing the area of ​​use, and can also save about 5 to 10% of the cost. It is most suitable for super high-rise buildings with more than 100 floors. The super concrete column is a layer of circular bread outside the ordinary coagulation column
