深圳蔚蓝海岸二期工程地下室车库在高层筒体间采用预应力框架结构,伸缩缝间距接近200m,为深圳地区当年单体面积最大的建筑结构之一。该工程施工完成后,预应力构件效果良好,基本未出现裂缝,取得较好的经济效益。在结构设计中采取微膨胀混凝土的合理措施,使预应力框架结构的伸缩缝延长。 Shenzhen Cote d’Azur Phase II basement garage in the upper cylinder using prestressed frame structure, expansion joints close to 200m spacing, for the year in Shenzhen area monomer structure of the largest one of the buildings. After the completion of the project, the effect of prestressed components is good, no cracks basically appear, and good economic benefits are obtained. In the structural design to take a slight expansion of concrete reasonable measures to extend the prestressed expansion joints of the framework of the structure.
