If I have a built-up tee section that is receiving a load such that the web (stem) is in compression, what is the allowable bending stress of the section if the b/t ratio is less than the noncompact limit of 127/(square root of Fy)? There is an entire appendix devoted to situation where...
My company is active in performing roadway inspection so we have many nuclear gauges and DCPs. We are now getting into building inspection. My question is regarding equipment for footing inspections. It seems that in our region, the pocket penetrometers are typically used for this test. From...
dear all,
I have a spindle axle with bearing attached to
it.now i have to carryout fea analysis.can anyone
suggest me how to simulate this problem.ie type of
element to be chosen is it a non-linear analysis.
thanks.and cheers.
Hi friends,
Is GI heavy class pipe suitable for water mist system?System pressure is about 20 bar and the application is in a underground services tunnel.Any advice will be appreciated.

I need help with using Com624 program that I have downloaded from FHWA web site. I am trying to assess pile behavior under 1 and 2 inch deflection once as a free head pile and once as fixed head pile. under "data for loading" submenue of the "analysis" menu there are 4...
Hi friends,
I am currently designing a campus cooling system of about 8000 tons.I intend to use distribution pumps of following capacity:
a)2nos varaiable speed drive pumps each of 3350 gpm@ 200 ft head(eqvt to 2x2000tons based on a delta T of 14.4F)
b) 1 no constant spped pump of...
Hi everyone,
I am designing a bridge with a simple span of 80 feet. the AASHTO loading is not a problem and is applied by the Book. The owner wants an type 3 dump truck loading applied also . the "type 3" weighs 33 tons (66000lb) front axle=14kips middle axle=26 kips and 12 feet away...
I am designing a continuous composite girder bridge.
Please tell me how can I analyse the composite girder for shrinkage
of concrete and temperature difference ? If you brief me shortly, it will be helpful to me.
I saw one report , converting the shrinkage into equivalent temperature difference...
I like to know which is to be checked whether Principal stresses or Von Mises equation when an element is subjected
to axial,bending stresses in two planes and shear stresses ?
I want to know where Principal stresses govern , where Von Mises equation govern ?
Please help me.
Hi everyone,
does the modulus of elasticity of steel vary with yeild strength???
I am working on astructure that is to be built with Grade 70 weathering steel (Fy=70ksi) is the "E" value 29000000psi or higer??
I really would appreciate your respose
Thank you all
I like to know the design and construction of the deep basements of depth about 10M below ground in the urban area.
Can any body tell me some reference books and any thing available in the net ?
Thanks
I like to know the procedures to make foundations on filled
soil. How to determine the bearing capacity and other soil parameters for the design of foundation.
While designing the bridges ( girder + slab),the Courbon method is used for the transverse distribution of vertical loads. How to design the cross girders for the lateral distribution of vertical loads.I want to know the concept and good reference material available in the internet.
Please help me
Im working on a bridge that will have large diameter CIDH piles (>10 feet) at the bridge bents. I used the LPILE program to come up with the P-Y curves. This site consists of alluvium (sand) over weak bedrock. My problem is converting the P-Y curves to Soil Springs. I need to come up with...
I have to design a steel beam which is supporting a concrete slab.That is the top flange is restrained against lateral displacement. Now I have to apply some load on the steel beam through a bracket . Thus there is some torsion is developed in the beam.
There are methods available to design the...
