ABSTRACT:- Reinforced concrete beam with transverse web opening is a facility that allows the services such as telephone lines air conditioning and ventilating ducts, to pass through the structure. As complementary materials, steel and concrete are a suited match; concrete is more corrosion resistant, with good compressive strength characteristics, but brittle (though it may show a little plasticity under loading [ CITATION Owe09 \l 7177 ]) and steel is more ductile, imparting some elasticity to a composite concrete-steel reinforced beam This video demonstrates a four-point bending test on an over-reinforced concrete beam.
