STAGED CONSTRUCTION
Construction Engineering
Crucial to the design of high-rise buildings is the analytical simulation of construction staging. A staged construction analysis enables the proper evaluation of the total and differential (elastic, creep and shrinkage) axial shortening of the walls and columns considering local conditions such as the relative humidity, age of concrete at loading, floor construction cycle and sequence of application of building superimposed dead loading.

Usually, the relatively lightly loaded core wall shortens lesser than the highly loaded columns. A staged construction analysis enables the proper evaluation of the total and differential (elastic, creep and shrinkage) axial shortening of the core wall and columns so as to avoid any unwanted long-term tilt in the floor plates between the core wall and the individual columns.
