or use VPN client to get around it.
Thanks

Thank you guys.
Buggar, Yes it is soil-cement mix. Based on test results 900 to 1000 psi is used for f'c.
I needed the allowable for working stress design so I can calculate the safety factor,but as dcarr82775 suggests
factors 0.4 or 0.45 is used for f'c to get that WSD allowable. I don't...
I am designing a CSM wall. we are using Plain Concrete provisions as there is no codes for Cutter Soil Mix walls.
I am using working stress design, to get a safety factor for applied stress over allowable stress.
I need to find the allowable compressive strength of plain concrete
I see...
Most precast septic tanks, and other tanks have openings in their top slabs; usually 24"diameter, but some upto 48" diameter; these openings need to be covered by concrete cover/plugs same thickness as the top slab; my question is such; is there a need for circumferential reinforcing around the...
I am designing a reinforced concrete foundation and frame structure to support a two story dwelling in a flood zone; columns are 16' tall to clear the flood elevation;
the contractor wants to use precast columns and beams to save time; I have researched the literature and couldn't find this type...
Can anyone help me in determining required minimum reinforcing in a precast slab. The slab in question is a cover for a pit. Loads are not significant. Minimum reinforcing governs the design. ACI code doesn't address this issue specifically.
I have a unique situation looking for assistance.
A precast concrete tank ( 10'x17' footprint and 9' high) is to be installed in ground, with 2' soil cover. Water TAble is at grade; calculation showed that buoyancy forces govern; hence the tank will lift up unles more weight is added. The...
Will someone tell me whether the buoyancy force increase with depth. I have a precast concrete tank where top of concrete is 3' below surface and the water table is at grade. the Tank is 9 feet deep and covers an area of 10'x80'. I calculate the buoyancy (uplift force) as...
Anyone familiar with the design of circular , eccentric manholes and catch basins? Which software is more suitable for designing and analyzing variuos shapes and forms of underground utility structures such as manholes, catch basins, risers, drywell etc.? H-20, and hydostatic loading need to be...
