| Summary: | In modem building nowadays requires many duct and pipe to provide a
comfortable accommodation. The dead space created between the beams and ceiling for
installing the ducts and pipe, this cause the overall floor height. Web opening in
concrete beam is the only solution to provide a clear place to install with no decrease the
floor clear height. There are a number of studies have conduct related to reinforced
concrete beam with web opening. This study aims to determine the deflection of
reinforced concrete beam with 3 small opening by using finite element softwareANSYS.
The beam model is simply supported beam with two concentrated and
symmetrical
loads. There are six elements of the beam been manipulated to form
different
modal. There are modulus of elasticity, reinforcing steel bar size at the bottom
and
surrounding the opening and concrete cover, apply loads, and shear link spacing.
The
effect of the apply loads is very significant and follow by concrete cover. However,
others
element is insignificant of affecting the beam deflection. Based on this study, the
effect of reinforcing steel bar size, shear link spacing and-concrete
.
strength is very
insignificant
and might be ignored, if the reinforced concrete beam with opening are
well
designed. |
