THEORETICAL BEHAVIOR OF COMPOSITE CONSTRUCTION PRECAST REACTIVE POWDER RC GIRDER AND ORDINARY RC DECK SLAB

This study displays numerically (or theoretically) investigation by using the finite element models for experimental work of composite behavior for hybrid reinforced concrete slab on girder from locale material in Iraq, ordinary concrete in slab and reactive powder concrete in girder, RPC, with steel fibers of different types (straight, hook, and mix between its), tested as simply supported span subjected under two point loading. Which ANSYS version 15.0 is utilized. By studying the compatibility between the experimental results and the theoretical results. As well as, parametric study of many others variables are investigated by using ANSYS (version 15.0), such as: changing the compressive strength of the slab, changing the main reinforcement of the girder, and changing thickness of resin bond layer between girder and slab. The results showed that the increasing of the grade of slab concrete from 25.8 MPa to (45, 55, 158)MPa the ultimate capacity increases by (7.5, 14.2, and 24.5) % and the deflection decreases to (10.6, 16.4, and 24.8)% for reinforced hybrid RPC girder with NC slab.
