CONSTRUCTION SIMULATION BY SEGMENTAL ANALYSIS

For multistorey buildings, the construction sequence is simulated. At each stage of the construction, as a new floor is added, the structure is analyzed up to the erected level only. As the erection proceeds level by level, the new member dead load effects are added to the stresses of the previous construction stage.

In taller building designs, ignoring the construction sequence effects can lead to substantial errors. For example, in a 30 level concrete frame, in the upper level beams, AMECO-17's segmental analysis produced moments that differed by 90% from those obtained without construction simulation.

Similarly, certain highrise steel frame structures are also sensitive to the construction effects. For instance, the American Express World Headquarters, bracing forces in the steel core framing would have been in error by more than 200%, were it not for AMECO's segmental analysis.
