ARCHITECTURAL PRECAST CONCRETE JOINT DETAILS

stages is an equalization or expansion chamber which must be vented and drained to the outside. Section 3.3 gives typical details of two-stage joints. It can be seen that the simplest form of a hor-izontal two-stage joint is the well prov-en shiplap joint. The rain barrier prevents most of the rain and airborne water from entering the joint.

LOAD DISTRIBUTION

By lateral we imply a direction transverse to the main reinforcement. Distribution reinforcement is located in the bottom of the deck slab. To determine the amount of distribution steel required, the amount of main reinforcement needed is multiplied by a specified percentage. 1. Main reinforcement perpendicular 2. Main reinforcement is parallel
