I know....Civil form has topics on thrust blocks, they still don't answer my question. Actually, this is more of a statics question.
I'm reading that to design a thurst block both static pressure and flow velocity must be account for.
Flow velocity I get, but I can't envision how static...
I realize a few threads have already been posted on this topic. After reviewing those threads I still have a couple questions I would like to clarify.
Quick summary:
30" inner pipe diameter, 75 psi max, 8333 GPM max
pipe inside building
thrust block needed at 90 degree turn
1: Per DIPRA 6th...
Hey folks,
I have a situation in which I am coping a W6 x 12 beam into another W6 x 12 beam. Due to eccentricity the connection will have shear and tension. I plan to use a double angle connection and have questions on both bolting and welding requirements.
BOLTED CONNECTION:
Per AISC equation...
I need to calculate Snet for a W6 x 12 top coped beam. Values are not listed in table 9-2.
As a check I did a hand calc. for a W8x10, dc=2 in, neglecting the fillets and taking the shapes as true rectangles. My Snet came to be 3.6 in. cubed as opposed to 1.54 in. cubed as listed in AISC table...
Anyone have any experience with thrust blocks, codes, tips, advice?
I've been asked to design one and honestly don't know where to start besides the location and size of the pipe and where the pad should be placed.
Thanks for any help.
If Lb falls inbetween Lp and Lr the Cb value is required to find the bending moment. Suppose the applied load to the beam is unsymmetric. I have a simple span with an off center point load.
Is the Cb = 12.5M/(2.5M+3Ma+4Mb+3Mc)Rm equation still valid or should I just rely on the AISC available...
Hey guys,
As an overview, there are series of clear water basins which gravity feed a pumping station. One of the clear water basins may need to be temporarily put of of service for repairs. The big question is, how will putting the clear water basin out of service affect the pumping station...
Hey fellas,
Just looking for some insite on how a point load distributes through earth. Please see the attached pic and let me know if it seems correct or not.
Hey fellas,
Quick question, maybe not a quick answer. I'm curious how to design a two-way slab, rebar T & B, with a manhole size opening. ACI 318-05 13.4 doesn't seem to be much help. The two-way slab needs to handle a truck load. Doesn't matter what type of truck I'm more interested in the...
Hey fellas,
I'm reviewing a concrete sewer chamber in which I have no prior experience. I'm looking for some experienced input. Please view both the plan view and secion. My thoughts are as follows:
1. The design seems to combine a chamber and a riser cone manhole, not sure how typical this is...
Hey Gentlemen,
I'm reviewing a stair submittal sent by the fabricator. The top landing is anchored to a concrete wall by a kicker. My goal is to check the adequacy of the connection (in particular the bolts anchoring into the concrete). As you can see by the attached pic the bolts are not...
I am currently surveying an underground clear water storage basin for cracking and potential cave in areas. Access is through manholes only. The basin is constructed of concrete vaults supported by columns all unreinforced. Worst case senario is that construction will need to be done with the...
The goal is to calculate the breakout strength of two embedded studs. This is applying to a plate embedded to a concrete wall with two studs attached anchoring horizontally into the concrete wall. This is to support a stairwell landing.
1.) I want to confirm the correct equaction to use, which...
