    Design Aids for Unreinforced Web Openings in Steel and

    The set of design aids presented allow identification of the ""neutral zone"", a region in the beam web in which openings with some particular characteristics do not reduce the beam strength. It leads to economic alternatives for web openings design, constituting a useful tool, meeting an important demand of steel designers. Design Example for Beams with Web Openings American Kussman, Richard L.; Cooper, Peter B. (1976). "Design Example for Beams with Web Openings," Engineering Journal, American Institute of Steel Construction, Vol. 13, pp. 48-56. DUE TO the increasing cost of energy and the difficulty of obtaining raw materials, economy has a high priority in all aspects of design.

    Repair Effectiveness of Damaged RC Beams with Web

    steel plates were used as repair materials with two types of configuration - hexagonal and rectangular - for each material. The beams contain a rectangular web opening at one of the shear spans. The externally bonded CFRP sheet and steel plate were found to be effective in repairing RC beams with a large rectangular web opening. Specifications for Structural Steel Beams with Web OpeningsSpecifications for Structural Steel Beams with Web Openings covers the design of composite and noncomposite beams with web openings. Basic design procedures involve determination of maximum nominal flexural capacity, maximum nominal shear capacity, and interaction of flexure and shear. Section properties are limited to ensure ductile behavior.

    Static and Dynamic Analysis Web Opening of Steel Beams

    According to the purpose of the opening and the structural designer, the shape of the web opening is decided. It is too easy to choose the shape of openings from regular shape whether it is circular or rectangular shape. The presence of openings in the web of steel beams decreases stiffness of the beam and introducing a larger deflection than in the steel web opening with solid opening.
