I have a gravity wall composed of concrete block, the total height will be about 40 feet.
The backfill at the bottom third of the wall will be filled with concrete for a width of 10 feet approximately.
For the stability calculations, I think I can assume some shielding from lateral loads...
There is a clause in the code that states:
A minimum area of flexural reinforcement, Asmin, shall be provided at every section where tension reinforcement is required by analysis.
My question (s):
What does it mean that the tension reinforcement "would be required by analysis"?
When this...
If I have a hollow concrete structure; 5 ft W X 10 ft L X 30 ft H that will be filled inside with soil, and nothing from outside "theoretically".
I need to calculate the earth pressure on all the sides, and wondering if the full lateral earth pressure will be developed within this limited...
I wanted to model an 8.67' X 31.5’ concrete slab with a 16,000 lb. load applied at the center and nothing else.
I did not apply any self-weight or load factors in this exercise
The slab will have fixed ends at all sides.
Can anyone explain why I am getting apparently a very low maximum...
I am checking the sliding of modular precast blocks wall, which are hollow blocks, filled with stones (less than 1").
What is the typical coefficient of friction between stones when it comes to sliding check?
Thanks
Hi,
I posted this in the Earth Retention Engineering forum, but I had no luck for three days.
I am calculating the seismic force on a gravity wall per AASHTO.
The concentrated dead load surcharge pressure distribution is not clear (to me!).
How can I estimate the maximum, and minimum pressure...

How can I estimate the maximum, and minimum pressure values for the trapezoid to calculate Fp?
Also, is Kaf is the same as Ka utilizing...
Hi All,
Anyone has the the historical sheet pile sections and properties, which have been used over the years and categorized by year range?
I recall I have seen something like this in the past. I appreciate if someone have it ans share..
Thanks
I have a round manhole, the base frame (round) is resting on 4 beams in a square arrangement. The bearing area on the concrete will be a segment of the circle on each side with maximum height of 6" from the edge of the beam (attached is a sketch).
Since the load is not spanning the entire beam...
I need to model a simple structure consists of slab, pile caps, beams, and piles in STAAD.
I am modeling the centerlines, but when I look into the 3-D rendering it does not look great. Elements appears to be at different elevations(page of the attachment).
What is right to model such...
Hi,
I have an HP pile in the water, 29 feet exposed height and assuming fixity at 20 feet below mud line.http://www.eng-tips.com/
The pile is encased by 24" diameter concrete from top until 15 feet down (almost half the exposed height is encased)
How to calculate axial load? How to calculate the...
I am looking for RC capping options for a PAZ combined steel sheet pile wall. The piles are about 1.5 m in diameter with 2 AZ-26 sheet pile in between. Since this would be on the water one of the options is to drop the face of the cap in front of the wall system to the water level which is...
AISC have a provision for members subjected to flexure and axial force given in Chapter H (H1.1)
The given formulas require that the combination of required strengths devided by the available strengths for both axial and moment not to exceed 1
Is there any allowance for slight overstress? (i.e...
Dear Colleagues:
I need to evaluate an admissible lateral load on a steel mono pile that will be used as a mooring dolphin for large ships. I set it up in Lpile software. The exposed height is about 55 ft,and the embedment into the soil is 30 ft. (85 total pile length)What is the criteria in...
I appreciate if somebody has typical details for existing steel sheet pile wall ...
The wall is about 6 feet high, currently no weep holes .. the wall has deflected at the top by about 3 inches and is attributed to hydro static pressure due to poor drainage ..
Thanks
I need to calculate ice load on structure at Hudson River in NY. I need to find typical characteristics of ice at Hudson River in terms of thickness, typical floating ice sheet dimensions, compressive strength, etc. I appreciate if anybody has some feedback or direct me to where I can find this...
I am looking for references on different types of mooring system of offshore floating structures in various depthes and seafloor types. I appreciate if there's recommended educational web links, textbooks, etc.
Thanks
What is the available classifications of graded riprap in NYS?
I have a rock gradation requirments given in Dmin, D50, and Dmax. I need to correlate this to state classification/ caategory if exists in the state code.
Thanks
