Equivalent Lateral Force Procedure...
Seismic Base Shear V= Cs x W
Where:
Cs = variable depending on accelerations,response modification, etc.
W = the TOTAL dead load (plus applicable portions of other loads)
---------
Fx = Cvx * V
Fx = Horizontal seismic force induced at any given level...
In looking at ACI318-02, I am a bit confused with regards to an item shown in the flowchart of Figure R5.3.
The item reads:
"Field record of at least ten consecutive test results using similar materials and under similar conditions is available"
This seems odd to me.
Isn't the point of...
Here's the situation.
A large base slab for a rectangular tank has been poured. The vertical dowels projecting out of the slab for the future walls have been cast, but unfortunately they have been improperly located such that they have 1.5" of clear cover as opposed to the specified 2" as...
For those of you that have designed arches by hand using the BIA technical bulletin 31, you know where I'm coming from on this.
Does anybody on here know of a software program available for design of brick veneer arches? The design procedure published by BIA is as tedious as it gets... it's a...
I have a question for you guys, if you have a minute.
Homeowner ABC has been living in an old house for several years. The home was originally built over 20 years ago, and the original ductwork and HVAC components have been in place ever since.
Homeowner ABC hires XYZ AC Company to install a...
When a wood prefab roof truss must be broken down into two pieces for shipping purposes, whose responsibility is it to provide the design for the piggyback truss to base truss connection? The structural EOR, or the truss designer?
Is there a specific procedure for checking "crushing" of composite metal deck? This would occur where the deck passes over the supporting member and directly over the member sits a wall inducing a large line load. The metal deck and slab are essentially sandwiched between the bottom...
Say I have a cantilevered W-section beam with a backspan of 25 feet and the cantilever extending 8 feet out over a column support. There is uniform loading (due to concrete slab, etc.) along the entire length of the beam, and there is a substantial concentrated load at the end of the...
Is it permissable to take a 15% increase in allowable stress of wale beams used to brace/support sheet piling around a 30'x32'x26'deep excavation? Obviously, the shoring is temporary, hence the increase. Any comments?
