I'm designing a pile cap abutment in RC-PIER, but I'm unsure how to input the material properties. In the material properties tab, there are inputs for concrete cap, concrete footing, and concrete pile. I have a concrete cap on steel H-piles. RC-PIER will not allow blank/zero input.
1) What should I input for footing material since I do not have a footing?
2) How do I properly input steel pile material properties in the concrete pile tab?
