Q

How would one calculate the minimum weight of the wall shown in the drawing? Code requirement that stabilizing moment is 1.5x the overturning moment

A

Correct. This is a three-part calculation. First, we must calculate the moment about point B. Then, we must calculate the weight of the wall needed to stabilize against this moment. Finally, we must apply the 1.5 factor of safety.

  • Step 1: Calculate the moment about point B.*
  • The overturning moment will equal the sum of moments produced by the lateral forces about point B. We calculate around point B because that is the point around which the structure would overturn, if forces acting from the left of the diagram were strong enough to overturn it.*

The force at the 2nd floor is 8 kips, and is 15’ away from point B along the Y-axis. The force at the 3rd floor is also 8 kips, and is 25’ away from point B along the Y-axis. The force at the 4th floor is 12 kips and is 45’ away from point B along the Y-axis. The equation is as follows:

  • M ov(B) = 8 kips x 15ft + 8 kips x (15ft + 10ft) + 12 kips x (15ft + 10ft + 10ft)*
  • M ov(B) = 8 x 15 + 8 x 25 + 12 x 35*
  • M ov(B) = 740 kip-ft*
  • Step 2: The stabilizing moment is given by the following equation, where ‘w’ is the weight of the wall needed to stabilize the structure. (We will use a capital ‘W’ in the next equation, which accounts for the factor of safety.)*
  • Since the wall acts upon the centroidal axis of the structure (that is, it is in the middle of the building), we must find the distance along the X-axis from point B to the wall. Since the building is 30 feet wide, we divide 30 in half to arrive at the distance of the moment arm.*
  • By definition, the stabilizing moment, M st(B), is equal to the overturning moment, M ov(B).*
  • M st(B) = w (30 ft / 2)*
  • 740 kip-ft = w (15 ft)*
  • 740 kip-ft / 15 ft = w*
  • 49.33 kips = w*

Step 3: Finally, we apply the 1.5 factor of safety. This is simply done by multiplying 1.5 times the stabilizing moment:

  • W = factor of safety (w)*
  • W = 1.5 (49.33 kips)*
  • W = 74 kips*

What is the easiest way to remember the difference between a Stack Vent and a Vent Stack?

A

Remember that the term “stack” in Vent Stack can be plural! (But a Stack Vent obviously sounds like one vent)

The singular Stack Vent is the portion of the soil stack above the highest plumbing fixture. It is literally a vent for the stack and is open to the outside at the top.

A Vent Stack (aka, a stack of vents) is a collection of vents from a number of fixtures that share one exterior outlet.
