某工程为回字形超长钢筋混凝土框架-剪力墙结构，长度达110m。通过采用限制膨胀率≥0.025%的补偿收缩混凝土，不设置变形缝，实现超长结构无缝连续施工，既提高了结构整体抗震性能，又加快施工进度，降低工程造价。
某工程為迴字形超長鋼觔混凝土框架-剪力牆結構，長度達110m。通過採用限製膨脹率≥0.025%的補償收縮混凝土，不設置變形縫，實現超長結構無縫連續施工，既提高瞭結構整體抗震性能，又加快施工進度，降低工程造價。

The superstructure of an engineering example is the rectangular-ambulatory-plane overlong RC frame-shear structure,and structure length is up to 100 meter. Shrinkage-compensating concrete with≥0.025%restrained expansion rate is used to cancel movement joint,and thus realize jointless and continuous constructing of overlong construction.The above measures not only improve the seismic performance of the structure,but also accxelerate construction process and reduce project cost.
