Title:Investigation On Shear Lag Phenomenon In RCC Framed Tube Structures
Author Name:Gyani Jail Singh, Sasankasekhar Mandal and Rajesh Kumar
Synopsis:
In the present study, a 40 storey RCC framed tube building has been examined. The shear lag phenomenon is analysed in the framed tube structures, by various methods and are reported. The detailed investigation of the phenomenon in the tubular buildings is lacking. As the height of the buildings increases, the lateral load (wind load) becomes governing factor for design. Positive and negative shear lag occur in the bottom and top portion of the building, respectively. As the height increases, axial force in column is immediately adjacent to the corner column increase and with further increase in height, it shifts towards central column. Some column of compression flange may also develop tension right from the support depending upon height of the structure. Columns in upper storeys are critical columns for the designer as they may develop tension. The quantitative estimate will help in the design to fix preliminary section dimensions of different structural members.
