Design of Beams of Long Span and Low Specific Strength

Journal of Applied Mechanics, 1945
Abstract The paper gives methods for the design of cantilevers of uniform strength in bending in those cases in which the weight of the beam cannot be neglected in calculating the bending moment. This occurs in concrete structures when the span is large and the strength of material relatively low.

Construction of Long Span Reinforced Concrete Beams

HKIE Transactions, 2008
Casting of long span reinforced concrete beams with large sections may produce considerable difficulties to the in-situ construction process, especially when the construction is supported on the base of quite limited capacities. Experience acquired from casting a reinforced concrete beam of nominal span 36 m is elucidated.

High-Strength Concrete Deep Beams With Effective Span and Shear Span Variations

ACI Structural Journal, 1995
Nineteen reinforced concrete deep beams with compressive strengths in the range of 41 MPa ≤ f' c ≤ 59 MPa (6000 psi ≤ f' c ≤ 8600 psi) were tested under two-point top loading. All the beams were singly reinforced with main steel percentage p = 1.23 percent and with nominal percentage of shear reinforcement ρ v = 0.48 percent.

Gravitational stresses in single span deep beams

Building Science, 1967
A theoretical solution for the gravitational stresses in single span deep beams using Fourier series has been given. Numerical results for different span to depth ratios are given and these have been compared with the photoelastic results given by Saad and Hendry [1], and the finite difference results of Chow et al. [2,3].

Beams Subjected to Follower Force within the Span

Journal of the Engineering Mechanics Division, 1972
Some unusual instability effects are shown to occur in beams subjected to a tangential follower force within the span. Depending on the support and load placement conditions either no flutter occurs at all, or the flutter stability boundaries are determined by a series of progressively higher order flutter modes.

Indirect Loading on Beams with Short Shear Spans

ACI Journal Proceedings, 1977
A study of the effect of loading and supporting conditions on the behavior and ultimate shear strength of beams with short shear spans is presented. Previous experimental work by the authors has been extended to include a shear span-to-depth ratio = 2. The overall findings of the investigation are summarized.

Test on 15m Span Composite Cellular Beam

2016
Cellular beams are the preferred form of long span construction in multi-storey buildings. For efficient design of composite cellular beams, asymmetric sections are often manufactured in which the bottom flange is larger than the top flange. A further innovation is in the use of 80mm deep deck profiles which allows beam spacing to be increased to 4.5m,
