This web tool carries out the design of simply supported composite beams to the Eurocodes. It is applicable to secondary beams subject to uniformly distributed loading, or primary beams loaded at midspan or third points. The slab is constructed with metal deck, which may be selected from the ComFlor range, or specified for other metal decks. All standards are as implemented by the UK National Annexes. At the execution stage the secondary beam compression flange is assumed to be fully restrained by the metal deck, and the primary beam compression flange is assumed to be restrained at load application points.
The beam may be unprotected or protected; a range of protection types and thicknesses may be selected. If the beam is unprotected, the software reports the time to failure, which may be compared to the required period of fire resistance.
If the beam is protected, two results are provided. Firstly, the critical temperature is reported, which may be used to specify the required performance from any protection system. The critical temperature is independent of the material of the protection system.
The option to select if the voids may be filled or unfilled and the shape of the protection system that is being considered is provided. These inputs will result in different critical temperatures due to different temperature distributions within the elements of the beam. Secondly, for the range of products available in the software, the time to failure is reported, which can be compared to the required period of fire resistance. If the beam is protected and a trapezoidal deck has been selected, the voids under the deck over the beam may be specified as filled or unfilled — unfilled is more onerous.
Although care has been taken to ensure that the calculated resistances are correct, users should verify the output. The Steel Construction Institute and other parties associated with this software and website assume no responsibilities for errors or misusue of this software, or damage arising from use of this software.

RAM SS - Steel Beam Deflection and Camber
The Euler-Bernoulli equation describes a relationship between beam deflection and applied external forces. The simplest form of this equation is as follows:. We use these equations along with the boundary conditions and loads for our beams to derive closed-form solutions to the beam configurations shown on this page simply supported and cantilver beams. The beam calculator uses these equations to generate bending moment, shear force, slope and defelction diagrams.
The beam calculator is a great tool to quickly validate forces in beams. Use it to help you design steel, wood and concrete beams under various loading conditions.
Also, remember, you can add results from beams together using the method of superposition. Of course, it is not always possible or practical to derive a closed-form solution for some beam configurations.
If you have a steel, wood or concrete beam with complex boundary conditions and loads you're better off solving the problem numerically with one of our finite element analysis tools.

Elastic Beam Deflection Calculator
Refer to the Ram Steel Beam manual, section The beam in question is a 20' long girder and the CDL stems from the beam and deck self weight. Thus the program cambers 0. The Live load deflection is calculated using the composite properties Ieff and is therefore a smaller total deflection even though the applied loads may be more than the CDL.
This Live load may already be reduced if the beam tributary area is large enough. Construction live loads are used in the Pre-composite strength check of the beam only, not in the initial deflection check. The Post Composite value is also based on the composite beam effective inertia. This is often referred to as the superimposed load. So long as the Live load deflection and Net Total deflection limits are OK, no warning will be given.
It is also worth noting that even with camber, this beam theoretically deflects 1. The program does not increase the construction dead load to account for the additional topping concrete that might occur from such ponding.
The applied loads should manually be increased where this is a concern. No, Ram Steel beam only checks the local deflection of the beams, not the cumulative deflection of the beams plus the deflection of the supports.
The Criteria - Camber controls whether to camber or not camber composite beams or non-composite beams for the whole model. In cases where you want no camber on specific beams consider adding a special deflection criteria with an initial deflection limit equal or less than the minimum camber and assign that deflection criteria to the beam in question:. All transfer dead and live loads affecting composite beams are part of the post-composite design.
For transfer columns, that typically makes sense since the lower level composite beam should be hardened by the time the upper level is loaded. For hanging columns it's not so clear cut, but the transfer load is still only considered in the post-composite design in Ram Steel. Transfer loads do not include the column self-weight since column design typically takes place after beam design. A point load for the estimated column self-weight is advised. In the case where a composite beam is designed non-compositely i.
