Hello Everyone,
Just a basic question on load combinations in Eurocodes as i am new to Eurocodes.
I have received the following loads from strcutural engineer.
Permanent Loads:
Vertical Compression (kN) = 50
Vertical Tension (kN) = 0
Horizontal shear (kN) = 0
Variable Loads:
Vertical...
Greetings to all,
I have a query about load testing. Is it correct to conduct a static pile load test on a pile which is already tested by dynamic load test. The final settlement attained is 0.1, 0.3 and 0.86mm in the three successive blows. The pile is a bored cast in situ pile.
If anyone...
Greetings of the day....
I am trying to make one dynamic SUM in excel.
i want to input the different depths in G & H column. The layers with SAND thickness should be returned in I column. the extra difference also should be included with in.
The sample file i have attached. I tried some...
Dear All,
I just want to understand why there is a restriction in ASTM D4633 Clause 4.2 Note - 1 regarding the limitation of the SPT hammer energy evaluation of the hammer in between 10 to 50. In definition of the N- value it is understood that the blows required for 300mm penetration by...

I am looking for the problems associated with foundations (for pile, open & box type) on shale (completely weathered to moderately weathered). So, what are the things to be kept in mind during geotechnical investigation for shale rock?
It is a elevated highway structure on...
Greetings to all!!
I received some Load test reports. The load test is conducted cyclic vertical. There was no instrumentation in the pile. Only information according to test conducted is, pile top settlement, rebound of pile after removing each load increment. So, to separate skin friction and...
Greetings to all.
The project location is majorly dominated by Sandy SILT with very less clay content (ML-CL). Silt is everywhere more than 55% and clay is less than 18%. The direct shear tests (DST) shows a C-phi behaviour of soil. The cohesion ranges from 5kPa to 10kPa and Phi ranges from 27...

Is there any freeware or any VBA or Python code for making soil profile ?
I used to spend many hours by making the soil profile and cross sections for working. If any good software with 3D viewing modes or any quick 2d profiling like by any codes is available please reply...
Hello Everyone,
I am currently working on a river bridge project. The location is a delta region. Scour depth is 40m. Pile dia adopted is 2m & 2.5m.
So to make the pile as a long pile, the critical length is used as the minimum embedment below scour level.
So 30m min. embedment is provided...
Greetings to all.
Is there any reference for the failure criteria of shallow foundations?
I mean three criteria (general, Local, Intermediate) are available. So what are the criteria to categorize these three in cohesive as well as cohesionless soils. For cohesionless soils we use angle of...
Hello all,
Is it possible to do the lateral pile load test on the same pile tested for vertical load test ?
if yes, please give your thoughts about it. (any reference will be very useful)
In EXCEL when i use a formula, to check one value i mostly check by EVALUATE FORMULA for the correct value is referred or not. but instead of doing that is there any other method or function or VBA available to that ?
For Example:
A1: 10
A2: 20
A3: -1.332 =Sin(A1)/Cos(A2)
But i want to show...
It is a bridge to be constructed in creek portion near sea in India. The fluctuation of water is there due to tidal variation. The bridge is a balanced cantilever.
Vertical load 1250t.
Lateral load 200t.
About the strata :

completely to highly weathered rock...
Greetings to all,
I am working on stability analysis of embankments.
Details about:
Location : Delta region of a river, High risk zone (Seismic), in between the two banks of river, approach to the main bridge
Purpose : for road vehicle movement (24 kPa live load)
Max height : 10m

Sir,
i want to calculate the overburden pressure at certain depth (reference C14) but including the effect of water table. As, below water table submerged density should be considered and above saturated density should be considered. So, i am looking for a formula which can calculate...
Greetings to All,
For pressuremeter test (prebored pressuremeter test) interpretation (undrianed shear strength) the reference state has been taken as horizontal earth pressure (P0) at that test depth for all strain calculations. This is the basic assumption taken by A.C. Palmer (1972), Ladanyi...
Greetings to the readers.
While conducting the pressuremeter test, the probe used to blast during the test. When i plot the corrected curve from raw data i got points up to mostly in the end of elastic zone or in some cases in between the strain softening zone only.
As the test doesn't crossed...
Respected Readers,

I am posting this for the question i am always wondering about.
I want to know how i can learn more and more in geotechnical engineering design practice?
Currently i am working from last 10 months, i am working in mostly infrastructure projects, means my scope...
Hello,
I want some reference(standard) for the u trough retaining wall. This is actually a abutment type of structure which will be back filled. This will serve the approach for the rail lines from embankment to bridge. It's 1200 meters long.
SO, i want any guidelines for foundation...
i have a retaining wall of 1230 m. i want to calculate the settlement for this.
i assumed as a strip footing but i am facing problems with fixing the factors in immediate settlement. Any thing regarding reference and methodology will be very helpful.
thank you
