Abstract

Abstract

Using project measurement of an actual, it is examined the vertical deformation of a tall steel reinforcedconcrete frame-core wall structure during construction． The results show that there is a difference in deformationmagnitude between the steel and concrete in steel reinforced concrete columns, and that deformation compatible timebetween concrete and steel is associated with the concrete strength grade: the higher the concrete strength grade, thelonger the time for deformation compatibility． The maximum value of column vertical deformation is 40710－6 , andthe maximum value of shear wall vertical deformation is 35910－6 ． The rate of vertical deformation is faster withinthe initial 14 d; and the ratio of vertical deformation to total deformation after finishing the construction of 42 floors forthe column and shear wall is about 0. 35 and 0.34, and follows a linear relation thereafter．
