It is in a hydraulic structure. Similar to an open rectangular box. Ext. wall height varies from 24' to 50'.
So, it is assumed that the reinforcement that is not fully developed above and below the construction joint cannot contribute to the strength of the wall. Even partially...
I want to provide a horizontal construction joint in a wall. There is a lap splice of the reinforcement at the same height. I think that the continuity of the steel will be established whether or not the wall is placed in lifts or monolithically.
Will the transfer of force between bars by bond...
Thank you,
I figured it out. The help file in my software states do not type the "if" statement use the programing toolbar button. I did this and the "if" was preceeded by a placeholder, which was irremovable causing an error. Anyway, I finally decided to type the "if" and it worked fine. Thank...
I am a new user and I am having trouble with an if statement:
determine:
if, v1<=v2 then, fb1
if, v2<v1<=V3 then, fb2
if, v1>v3 then, fb3
write:
the result for fbn=xxxxx
As a rule of thumb (depending on the mix design), false work for a soffit or walls supporting vert. load should not be removed until the concrete has reached 90% design strength (14-20 days), walls not supporting vert. load can be stripped at 70% design strength (usually around 6-9 days).
Thank you,
I proposed a similar idea. Since, we have #5 hairpins 24" OC EW. I thought that we could use those to absorb the vertical load or increase the size of the hair pins. However, our steel sub. does not think that is a stable approach. I will look into that option and if it is $$$...
Slab dimensions: 144' (trans.) x 72' (long.)x 8' (deep)
Top Bar Mat: 3 layers: #11 (trans) @ 8" oc
#10 (trans) @8" oc
#9 (long) @8" oc
The top mat of bar will deform out of tolerance, therefore it must be supported. In order to support the mat...
