Abstract:
The article provides a method for determining effective moment of inertia Ie for calculation of in-plane wall deflections using unfactored load. The method results in a map of the cracked concrete zones, and it allows calculation of Ie values that vary with the extent of cracking. The method provides a smooth transition between cracked and uncracked section properties, and it is suitable for manual calculations as well as computer models.
