Types of Beams

Cantilever Beam
Cantilever Beam

A cantilever is a beam supported on only one end. The beam transfers the load to the support where it has manage the moment of force and shear stress. Moment of force is the tendency of a force to twist or rotate an object.

Continuously Supported Beam
Continuously Supported Beam

Due to the beams top flange beam supported by the concrete floor it is actually continuously restrained along its length, meaning that the section capacity is approximately equal to the member capacity, let us say 200kNm.

Earthquake Load

Example 1 Earthquake Load Combinations: Strength Design §12.4.2.3 2. Strength design moments at beam end A for seismic load combinations a. For the governing load combination when the signs of Q E and D are the same 1.42D + 1.3Q E + 0.5L with D = M D = −100, Q E = M QE = −120, and L = M L = −50 M A = 1.42 (−100) + 1.3 (−120) + 0.5(−50) = −323 kip-ft b.

Fixed
Fixed

The Beam which has no freedom to rotate at ends is a Fixed Beam.The End Connections are provided with reinforcements to restrict the end rotation or tilting.The Torsional Reinforcement is adequately provided at end connection . No lateral movement is allowed in the fixed beams.

Live Loads (LL)
Live Loads (LL)

Live loads can be prescribed to any structural element (floors, columns, beams, even roofs) and will ultimately be factored into a calculation of gravity loads, which we’ll explain below. We measure uniform live loads as pounds per square foot (psf).

LOAD TYPES
LOAD TYPES

Cantilever beams a structure member of which one end is fixed and other is free. This is one of the famous type of beam use in trusses, bridges and other structure member. This beam carry load over the span which undergoes both shear stress and bending moment.

Over Hanging
Over Hanging

Single Overhanging Beam: It has two supports, hinged at one end, roller at other end. Overhanging portion at any one of the supports. Loads can be applied on overhanging portion and can be converted to equivalent moment at the support. Moment and Reactions are same as that of Simply Supported Beam. Double Overhanging Beam: This type of Beams will have over hangs at both the support. Both the Overhanging beams will have rotation at supports.

Settlement Loads
Settlement Loads

Dynamic Load Success Intro Thick Beam: The thicker a beam, the less likely it is to bend. Thick beams are used in structures that experience live and dynamic loads. Dynamic Load Success Thick Beam: The thick beam absorbed the vibrations caused by the dynamic load and prevented the structure from bending and galloping wildly out of control. Wind Load Failure Intro When wind blows on a structure, it is called wind load. Wind loads push horizontally on a structure.

Simply Supported Beam
Simply Supported Beam

A simply supported beam is a type of beam that has pinned support at one end and roller support at the other end. Depending on the load applied, it undergoes shearing and bending. It is the one of the simplest structural elements in existence.

Snow Load (SL)
Snow Load (SL)

Snow Load (SL) The magnitude of the snow load will depend upon the latitude and altitude of the site. In the lower latitudes no snow would be expected while in the high latitudes snow could last for six months or more.

Thermal Loads
Thermal Loads

Thermal loads on the Surface Loads spreadsheet induce in-plane stresses in the plate. The difference between the applied thermal load and the ambient temperature is the stress inducing temperature. For plates, you cannot define start and end locations for the thermal load the way you can for member thermal / distributed loads. Thermal Force Calculation. The joint temperatures recorded on the Joint Coordinates Spreadsheet define the ambient thermal state of the structure.

Wind Load (WL)
Wind Load (WL)

RE: Effect of wind loads on beams KootK (Structural) 24 Dec 16 17:20 If the top of the beam is restrained by a competent diaphragm, as is often the case, then it's really beam torsion that is the issue rather than weak axis flexure. In that case, I treat it as jayrod has described and the method is usually coined the bi-moment method.
