The construction process in that core-tube elements build prior to horizontal beam slab especially all sorts of treatment methods of the construction method are introduced.At the same time all sorts of anchorage depth of codes and the structural safety problem of temporary structures during the construction phase that resulted from out-of-step construction of as core-wall column beam and slab are analyzed.It is advised that construc...
