Hi, I have a Tz Qz and Py curves all in kN/cm. However, SACS ask for input data for Tz and Qz in kN/cm2. What should I do? should I divide Tz data by pile circumference and Qz by the corss-sectional area of the pile end? I would really appreciate if someone couuld give me a good and reasonable explanation of the Tz and Qz inputs. Many thanks in advance. Ali
