Steel Beams with Web Openings
The responsibility of a Structural Engineer lies in not merely designing the structure based on safety and serviceability considerations but he also has to consider the functional requirements based on the use to which the structure is intended. While designing a power plant structure or a multi-storeyed building, the traditional structural steel framing consists of beams and girders with solid...
متن کاملShear Strength of Reinforced Web Openings in Steel Beams
The floor beams of steel buildings, cold-formed steel floor joists in particular, often require large web openings, which may affect their shear capacities. A cost effective way to mitigate the detrimental effects of such openings is to weld/fasten reinforcements. A difficulty associated with an experimental investigation to establish suitable reinforcement schemes for openings in shear zone is...

متن کاملFhwa / in / Jhrp - 88 / 6 - 1 Structural Behavior of High Strength Concrete Prestressed I - Beams
This report deals with the evaluation of the ultimate behavior of AASHTO I-beams with concrete strengths up to 9000 psi. The relevant AASHTO and IDOH design specifications are thoroughly evaluated based on the results of this research. The findings of this study remark the many beneficial implications of the use of higher strength concrete in precast prestressed AASHTO I-beams. Higher strength ...
