Continuous Beam Design Example Using ASDIP CONCRETE

By: Javier Encinas, PE | October 17, 2017 ASDIP CONCRETE is a structural engineering software for design of concrete members. ASDIP CONCRETE includes the design of multi-span continuous beams based on the latest ACI 318 provisions. The design of continuous beams may become cumbersome and time-consuming, since it involves the analysis of the beam to find the moments and shears, and the application of the Code provisions to design the reinforcement. This document is a step-by-step overview of a design example of a typical continuous beam using ASDIP CONCRETE. As an example, let's consider a continuous beam, [...]

How to Use the Pre-combined Load Feature in ASDIP Software

By: Javier Encinas, PE | May 16, 2017 ASDIP is a structural engineering software for the design of structural members based on the ASCE 7 load combinations. But what about if you don't want your loads to be internally combined? This blog post discusses this important feature in ASDIP software. Structural engineering is all about calculations with loads, which are classified in different types, called Load Cases, such as Dead, Live, Snow, Wind, Seismic, etc. Typically the calculation results are generated and stored individually per each load case. These load case results are then affected by load factors in order [...]

Anchor Rod Design: Overview of the ACI Seismic Provisions

By: Javier Encinas, PE | January 9, 2017 The seismic design of anchor rods is included in the ACI 318 code, 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 is an overview of the ACI 318 seismic provisions that affect the design of anchor rods. 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. The seismic provisions apply to anchors in structures assigned to [...]

Bearing Walls Under Out-of-Plane Loads: A Design Overview

By: Javier Encinas, PE | December 13, 2016 Bearing walls are structural compression members which also may resist out-of-plane lateral loads. The resulting moments are referred to as weak-axis bending. A tilt-up wall panel exposed to wind is an example of this type of wall. Per ACI 318-14, bearing walls may be designed as compression members using the strength design provisions for flexure and axial loads, like columns. Wall design is further complicated by the fact that slenderness is a consideration in practically all cases. This document covers the design process of this type of concrete walls. Our [...]

Anchor Rod Design – The Complex ACI Provisions (Part 2)

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 [...]

Anchor Rod Design – The Complex ACI Provisions (Part 1)

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. [...]

How to Design Concrete Columns Using ASDIP CONCRETE

By: Javier Encinas, PE | August 11, 2016 ASDIP CONCRETE is structural engineering software for design of concrete members. ASDIP CONCRETE software includes the design of concrete columns based on the latest ACI 318 provisions. Following is an overview of the steps required to design uniaxial and biaxial concrete columns using ASDIP CONCRETE. Click To Enlarge Select the column type, either Rectangular or Circular. Enter the column dimensions and reinforcement in the Geometry tab. Specify the member length and effective length factors. ASDIP CONCRETE offers an At-a-Glance presentation of results, organized by topic. [...]

Concrete Columns: Structural Design Overview

By: Javier Encinas, PE | July 21, 2016 ASDIP CONCRETE includes the design of concrete columns. This structural engineering software is based on the latest ACI 318 provisions. This article is an overview of the structural design of concrete columns subjected to concentrated loads and moments. Columns are structural compression members which transmit loads from the upper floors to the lower levels and then to the soil through the foundations. Since columns are supporting elements, failure of one column in a critical location can cause the progressive collapse of adjoining floors. Normally columns are subjected to combined bending and axial load. These [...]
