Structural Steel Design

By: Javier Encinas | November 7, 2016 The design of anchor rods has become more complex with the development of the ACI 318 anchorage provisions. This is the second part of our post regarding the design of anchor rods. In the first part we covered the ACI provisions for the design of anchor rods in tension. Now we will cover the design of anchor rods in shear, as well as the tension-shear interaction. Our software ASDIP Steel will be used to support our discussion. How do you calculate the shear in anchor rods? The lateral forces acting on a structure [...]

By: Javier Encinas | October 2, 2016 The design of anchor rods has become complex and cumbersome with the development of the ACI 318 provisions, originally in the Appendix D of the ACI 318-11 and earlier, and now in the Chapter 17 of the ACI 318-14. This document covers the required steps in the process of the design of the cast-in anchor rods normally encountered in column base plates. The anchor rods are usually subjected to a combination of tension and shear forces. The ACI treats separately tension and shear, and then it combines both effects in an interaction diagram. [...]

By: Javier Encinas, PE | January 30, 2016 ASDIP STEEL includes the design of base plates as well as the anchorage system. This blog post covers the principal design steps. This structural engineering software is based on the AISC Design Guides # 1, Blodgett "Design of Welded Structures", and the ACI 318-11 Appendix D. Base plates are structural elements at the bottom of columns to spread the concentrated load over a larger supporting area, so that the bearing stresses are under the acceptable limits. Depending on the type of frame the column belongs to, the base plate may be subject to compression, [...]
