The code, is very vague when it comes to the lateral tie spacing vs longitudinal bar requirements. When you read Sokai and Sheikh 1989 publication I think it becomes very apparent that more direction is needed in this area. 16db in my case allows for 22" transverse spacing with 6" longitudinal...

I have a reinforced drilled concrete pile that is free at the head and embedded into sandstone for 16 ft. When I view the Pile deflection to depth chart it is giving me a negative deflection of 2.4 in how is that possible with rock. I have attached the image. I would have suspected it to...
