I'm now designing marine pipeway trestles, supported by piles. Is there anybody to give me some idea to reduce number of piles and/or structures? Normal design shows 4 nos. of batter piles per one bent. Thanks in advance.
Hi! All;
Is there any guy to let me know why arabian peninsular conturies use bored pile instead of the steel pipe pile or the precast prestressed spun piles?
Is there any corrosion issues on this common practice
or any other deliverable issues for the pc piles?
Any responses would be...
Is there any body to help me to design precast concrete piperack?
- connection details for column and spread footing
- connection details for column and longitudinal beam and also trans beam
Any comments and/or information would be helpful

Factually, immersed tube will be designed for seawater intake and we are now considering direct gravel foundation under the sea of depth 20m.
If you have any information and experience...
Hi,
I've seen that almost turbine foundation has been supported using bored pile, not concrete spun pile.
If you know the reason why, please let me know. What are the restrictions to use concrete spun driven pile for heavey vibratory equipment foundations.
Dear all,
I'd like to find the economical method to excavate the rock under sea condition. Due to the vibration restriction, explosives cannot be used. 1.0 kine is the criteria for the vibration.
If you have any idea, let me know.
Is there any body to help me to conduct the structural analysis for single cable with fixed end support using STAAD Pro?
My questions are
1. in 'geometry', how to input the geometry of cable?
in 'member specification cable', how to get the initial tension force?
Before running the...

Dear all,
I'd like to design of pipe bedding on very soft clay stratum in coastal region.
There is very soft clay ( c = 0.5 kg/cm2, SPT N=0~2) of 10 m thick depth.
Water depth will be less than 5m.
Any experience like this matter would be helpful to me.
Dear all,
Is there any one to help me on this matter.
Recently I have to design concrete foundation in Indonesia under seismic conditions.
However there is no information for local seismic spectrum of Jakarta (UBC Zone 4, as per UBC, Indonesia Seismic Zone 4) on the web.
Peak acceleration of...
Hello All,
In API 650 Section 3.11, wind load is specified based on 160 km/hr. But not mentioned 3 sec gust or 10 minutes average wind speed.
Factually, I would like to conversion my wind speed "x" (API maximum speed less than one minutes) to API general calculation speed, e.g., (x/160) to get...
Dear all,
In general details, pretensioned wires shall not be cut during the cut-off for Pretensioned Spun Concrete Pile. Wires shall be connected into the raft footing for connectivity between pile and concrete footing.
However, if we cut the wires the cut-off elevation, then how pile head...
Is there any body to help me to design the earth mound tank foundation?
I would like to know the relevant criteria, design procedure, etc.

Dear All,
During the pile driving, some of piles might be installed out-of-plumbness or out-of-batterness given in specifications, e.g., 1/50.
Could somebody give me some idea to evaluate the as-built pile capacity on deviated piles, e.g., 1/40 or less to its plumbness or batterness?
Hi,
I would like to know the min. requirements on pipe jacking under existing canal/river/stream.
Actually, I would like to know the min. clearance between natural alluvial stream bottom and jacking pipe crown.
Actually, stream width is 30m, its depth is about 1m and its bottom is natual...

Hi,
I'm working in Soil Improvement Proposal in Sri Lanka.
The land was reclamated on 4m thick peat (N value about 3) and swamp, using beach sand 2m thick (N value about 7). Below peat stratum there exists 6 m thick silty clay (N value about 8 to 16). Weathered rock is 16m below ground level...
