Strap Footings: A Very Useful Structural System

By: Javier Encinas, PE | May 8, 2016 ASDIP FOUNDATION includes the design of concrete strap footings. This structural engineering software is based on the latest ACI 318 provisions. This post covers the steps in the design of strap footings when subjected to a combination of vertical loads, horizontal loads, and bending moments. A strap footing usually supports two columns, so it's a special type of combined footing. If a property line exists at or near the edge of an exterior column, a normal isolated footing would be placed eccentrically under this column and it would tend to tilt. This [...]

Combined Footing: An Important Structural Design Element

By: Javier Encinas, PE | April 24, 2016 ASDIP FOUNDATION includes the design of concrete combined footings. This structural engineering software is based on the latest ACI 318 provisions. This post covers the steps in the design of combined footings when subjected to a combination of vertical loads, horizontal loads, and bending moments. If a property line exists at or near the edge of an exterior column, a normal isolated footing would be placed eccentrically under this column and it would tend to tilt. This problem may be prevented by supporting this column together with an interior column on a [...]

ASDIP Project Manager – The Core of the Software

By: Javier Encinas, PE | March 28, 2016 ASDIP is structural engineering software for member design. When ASDIP opens, a window pops up showing a menu bar and icons at the top, some buttons at the left, a tree at the right, and more buttons below the tree. This is the ASDIP Project Manager, as shown in the picture below. This blog post covers the purpose and capabilities of this part of ASDIP software. What is the purpose of the Project Manager? In ASDIP software all project information, including calculations, settings, preferences, etc, is stored in a [...]

Cantilever Retaining Walls: An Overview of the Design Process (Part 2)

By: Javier Encinas, PE | February 21, 2016 ASDIP RETAIN is structural engineering software for design of retaining walls. Competent design of retaining walls can maximize land use and substantially increase property value. This is a two-part blog post. In part one, Javier reviewed the basics of earth lateral pressure theories and overall stability checking. This second part of the article covers the typical loads in a retaining wall, and the structural design of the different components. What loads act on a retaining wall? Ordinarily, retaining walls are subject to surcharge loads at the top of retained mass. A [...]

Cantilever Retaining Walls: An Overview of the Design Process (Part 1)

By: Javier Encinas, PE | February 21, 2016 ASDIP RETAIN is structural engineering software for design of retaining walls. Retaining walls are structures designed to bound soils between two different elevations. A retaining wall is mainly exposed to lateral pressures from the retained soil plus any other surcharge. This article discusses the design of either concrete or masonry cantilever retaining walls. A typical retaining wall is composed of four main components: the Stem, the Toe at the front of the wall, the Heel at the backfill side, and the Shear Key. The images below show the geometry of a [...]

Concrete Continuous Beams: A Structural Design Challenge

By: Javier Encinas, PE | February 14, 2016 ASDIP CONCRETE includes the design of continuous beams. This structural engineering software is based on the latest ACI 318 provisions. This article covers the steps in the structural design of concrete continuous multi-span beams subjected to concentrated and distributed loads. Beams are structural elements that support loads applied transversely to the beam axis, which produce a combination of shear and bending stresses. Concrete beams are usually continuous, this is, they span between multiple supports acting structurally as a single element. This is possible because the rebars are placed continuously through the supports, [...]

Spread Footings Under Biaxial Bending: A Complex Design Subject

By: Javier Encinas, PE | February 7, 2016 ASDIP FOUNDATION includes the design of concrete spread footings. This structural engineering software is based on the latest ACI 318 provisions. This article covers the complexities inherent to the design of spread footings when subjected to a combination of vertical loads, horizontal loads, and biaxial bending. For a simple spread footing with a vertical compression load, the resulting bearing pressure is uniform and the shear and bending can be calculated easily by hand. If the column is at the corner of a building, then biaxial moments could be transferred to the footing. [...]

ASDIP STEEL: Base Plate and Anchor Rod Design

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, [...]
