Fatigue Performance of Reinforced Concrete T-Girders under

This paper examines the performance of reinforced concrete girders under cyclic loading. Seven T-girders were casted and tested. All girders were loaded under different constant cyclic loading in the midspan with the load ratio of 0.14∼0.23 and frequency of 3∼4 Hz. The study shows that the longitudinal reinforcement fracture is the main cause of girder rupture.

François Coignet's Reinforced Concrete House | Amusing Planet

The ancient Romans used concrete to build vaulted roofs, arches and great domes. The Pantheon in Rome, built in the 1st century, is the largest un-reinforced concrete dome in the world, and it's still standing after more than two thousand years. Many Roman structures that survive to this day were built with concrete, or had a concrete foundation.

Steel Fiber Reinforced Concrete FAQ

Steel Fiber Reinforced Concrete FAQ When subjected to tensile stress, unreinforced concrete will crack and fail. Since the mid 1800's steel reinforcing has been used to overcome this problem. As a composite system, the reinforcing steel is designed to carry the tensile loads. Steel fibers have been used for a similar purpose since the 1970's.

What are the Causes of Cracks in Reinforced Concrete Slab

1. Poor Concrete Quality. Compromising with the concrete quality is one of the reasons for crack developments in reinforced concrete slabs. Poor concrete quality results in lower concrete strength, specifically, the tensile strength. As a result, the tensile strength of concrete reaches its maximum limit at a very low magnitude of stress.

How to Reinforce Concrete - wikiHow

For your concrete to be adequately reinforced, the rebar needs to be positioned closer to the center of your slab rather than the bottom of it. Use chairs that will position your rebar about in the middle of your slab. For example, if you plan to pour 4 inches (10 cm) of concrete, use chairs that are 2 inches (5.1 cm) high.
