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

(The same question was posted in Civil Engineering other topics) Hi, I'm looking for some information to get the appropriate gravel foundation for immersed tube tunnel. Factually, immersed tube will be designed for seawater intake and we are now considering direct gravel foundation under...

Hi, I'm looking for some information to get the appropriate gravel foundation for immersed tube tunnel. 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...

Is there any reason to choose the bored pile against lateral loading, such as seismic load?

Thanks for your reply. On your reply, only economic reason would be considered. How about the pile size-bearing capacity-lateral capacity on each case. Waiting your reply.......

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...

Thank you, "fndn". As you noted, c value in previous post was incorrect. factually c=0.05 kg/cm2. SPT N-value is 1 to 2 of very soft clay. If you have any experience, please let me know.

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 Mr. Bob, Could you please let me know what ASCE code you mean. Regarding the tsunami, your experience would be helpful to me. For your further response....

Does anyone know where I can get SNI-1726-2002 Seismic Design Code of Indonesian National Standard. Thanks

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...

Indonesia local code zone 4 is different from UBC Zone 3. So far, I have no information on this matter.

Thank you Mr. Braune. Your answer would be quite helpful to me. Then, which API code number specify the maximum wind speed less than one minutes? Please let me know. Thank you again.

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...

Thank you, Zambo! Compared with your comments, such as "common detail", in Japn details, pretensioned wires shall not be cut-off for Pretensioned Spun Concrete Piles. If you have any web-site on said details, please let me know. For further help....
