General Requirements


Some main concepts include:

  • Excavation Safety: Except for excavations in rock, anything deeper than 5 ft must be stabilized to prevent cave-in. This may be achieved by providing appropriate earth retention systems or sloping at appropriate rates. This is determined by the depth of excavation, soil type, and other requirements. 1926 Subpart P – Excavations

  • Fall protection: Drop-offs must be protected from fall based on the height of the drop. Some examples of protection include temporary fences, nets, or lifelines. 1910 Subpart D – Walking Working Surfaces and 1926 Subpart M – Fall Protection

  • Power Line Hazards: For power lines which are electrified, all construction activities must be a minimum distance from the lines. This is based on the voltage of the lines. Typically the safe operational distance is 10 ft. for lines less than 50 kV and typically 35 ft. for lines greater than 50 kV. 1926 Subpart V – Electric Power Transmission and Distribution

  • Confined Spaces: Anyone required to enter confined spaces must be appropriately trained and equipped. Oxygen must be monitored and kept at an acceptable level. Subpart AA – Confined Spaces

  • Personal Protective Equipment (PPE): Equipment required by any personnel present on a job site. Examples are acceptable head protection and steel toed shoes. 1910 Subpart I – Personal Protective Equipment

Eccentrically Loaded Bolts


The bolt which will see the largest resultant force in a bolt group is the upper most bolt on the side of which the force is applied

Vp = vertical force per bolt = P/N

P = applied force (kips)

N = number of bolts

Ve = Force due to eccentricity = Pexc/Io

Xc = distance in X direction from centroid of bolt group to the subject bolt

The moment of inertia the sum of the distances of all bolts in the x and y directions if all bolts have the same diameter. Sum the distances of each bolt to the appropriate neutral axis:




Elongation and Contraction due to Axial Loading


The elongation or contraction of a beam due to an applied force is determined from the following equation:

D = PL/AE

P = applied force (kips)

L = length of beam (in)

A = cross sectional area (in2)

E = modulus of elasticity (ksi)




Elongation Due to Thermal Loading


The thermal elongation or contraction for steel is determined by the following equation:

D = Loa(t1 - to)

Lo = original length of beam (in)

a = coefficient of thermal expansion

t1 = new temperature (degrees Fahrenheit)

to = original temperature (degrees Fahrenheit)




Composite Beams


For composite members, the stresses in the beams can only be determined by analysis of similar materials. To do this, the stronger material should be converted to an equivalent area of the weaker material. This is done using the ratio of the moduli of elasticity n = E1/E2

Then calculate the equivalent width of the weaker material bequiv = bn

The member can then be analyzed as a single material.




Torsional Shear





Surcharge Load





Deflections


  • Not all deflections are covered under beam chart equations
  • Moment Area Method can be used for the determination of angle and deflection
  • First draw the moment diagram
  • Determine the M/EI diagram by dividing points on the moment diagram by EI
  • The angle between tangents of two points is the area of the M/EI diagram between points
  • The deflection of a point from the tangent of another is area of the M/EI times the distance from the centroid of this area to the desired point of deflection




Horizontal Shear Stress


Horizontal shear stress

t = VQ/Ib

V = Applied Shear Force (kips)

Q = First Moment of the Desired Area = ay.

a = Cross Sectional Area from Point of Desired Shear Stress to Extreme Fiber (in2)

y = Distance from Centroid of Beam to Centroid of Area “a” (in)

I = Moment of Inertia of Beam (in3)

b = Width of Member (in)
