Floor Joist Cantilever Table. Structural engineering is a complex process that is vital to the construction of any residential dwelling. The knowledge base of the structural engineer aids in the calculation the values and measurements of the construction materials, their placement within the structure, and the types of materials selected for the project.
Calculating the necessary measurements and properties of construction materials for a residential dwelling is a complex and time-consuming process.
For example, when calculating the necessary size of I beams in residential buildings, you must consider multiple factors:
* maximum bending moment of the beam
* maximum deflection of the beam at the center of the span
* width, length, and depth of the beam
* moment of inertia
* constant psi rating for the material the beam is comprised of
You must also consider the exterior dimensions of the home, the span if the beams and floor joists the dead and live loads for the structure, and the design style of the roof. If any interior walls will support the weight of the roof, this will affect the necessary I beam size throughout the residential dwelling.
Required calculations for determining the size of a residential steel beam include the allowable bending stress for structural steel, the moment of inertia, and the section modulus of the required beam.
A structural engineer generally performs these calculations. Certain computer software designed specifically for the calculation of
* beam design
* floor beam span
* rafter design
* header size and span
* floor joist load
* cantilever floor joist load
* residential I beam spans
are useful for quickly calculating these values.
Determining Building Materials
Steel and solid sawn wood are the traditional construction materials used in creating structures. Modern technology has resulted in the emergence of new composite materials and combinations of natural materials that improve the construction process, cost, weight, strength, and stability of a structure.
Solid sawn wood, structural composites, tube steel, solid steel, glulams (glued- laminated timbers), manufactured beams, and I joists are all used in differing combinations during the construction process.
Since each of these materials behaves differently under the stress of a load, calculating the required measurements and values for construction becomes even more complex. The physics behind the effects of weight, wind, water, temperature, and snow directly affect the construction process.
Residential dwelling construction requires a broad knowledge base, prior construction experience, and an understanding of the physics related to the construction materials and the forces that affect them.

This type of racking system consists of heavy duty steel girders for the frame and heavy duty steel projected arms bolted at one end to the frame. Heavy and long items or materials are placed horizontally across the projected arms. These projected arms are adjustable so as to allow several rows or layers of stacking in the same floor space.
Cantilever racking systems are both cost effective and space saving, adding to their desirability for industrial storage. I’m sure you have seen these racking systems when you go shopping, for example, at the DIY home improvement stores. They are the ones on which you see lumber planks and boards, metal framing strips, copper piping, etc stacked. Long, heavy pieces of lumber, metal shelving, wood shelving, drywall and other building materials are stored easily and in a space saving manner by the use of this type of storage system.
These storage systems can be painted using a standard set of colors and can be galvanized to protect and give the system better endurance for outdoor industrial storage uses. The adjustable arms make it easy to store items of different sizes and thicknesses in the same floor space. They can be constructed to your specifications for any storage need – large or small.
Cantilever racking systems are built to hold a great deal of weight. Many of these industrial storage systems boast weight capacities in excess of 30 tons per upright. Storage of plumbing and electrical components, such as copper pipe, metal and plastic conduit and plastic piping are easily and safely accomplished by the use of these systems.
How does this type of storage system support so much weight? The design of the system includes three heavy gauge steel uprights with horizontal bases. The adjustable arms are also made of the same heavy gauge steel as the uprights. The arms are bolted in place using heavy gauge steel bolts and a special bracing system at one end of the arm beam. It is the combination of weight distribution by the design of the unit and the heavy gauge steel used in the components that work together to provide the resulting strength and support capacity. This construction allows Cantilever racking systems to be used in warehouse storage uses as well as industrial storage applications.
