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...
Yes sir.
It helped a lot. Saved lot of time. I have added some filters in to it and works very well.
Many many thanks to you for the help & giving your time.

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...
to be very specific, The client want to have a option for recharge wells in that urban area for recharging the GWT. So if the GWT rises then the soil will get saturate. SO i may need to think of analyzing with undrained analysis. If they rule out the option of raising the GWT, then the soil is...
Thank you retired13 for the references.

Considering mostly the skin friction only, as end bearing have many issues like base cleaning and all.
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...
Yes the scour depth is design scour depth (2 times the scour depth obtained by Lacy's method). The scour calculation is based on silt factors and discharge. Silt factors for cohesionless soil is taken from mean dia of particle (from grain size distribution) and for cohesive the shear strength is...
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...
According to my view, i will design the pile as fully friction pile in case of soil.
If pile terminates in clay strata; having completely clay above founding level, then friction contribution will be more as compared to end bearing so it will be friction pile.
The contribution of sand layer in...
Sorry for not being clear on my question.
The bearing capacity equation given by Terzaghi is for strip footing, but the factors help us to change the capacity to our requirement.
He considered general shear failure and local shear failure.
So, while calculating the bearing capacity how to...
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...
If i understood properly, irrespective of predicting deflection along the pile the pile measurement at pile head (deflection, slope, B.M.) can allow you to produce a pile soil response to predict the deflection and capacity. The reference could be done to
L. C. Reese and W. R. Cox, "Soil...
