Are You Designing Your Anchor Rods Correctly?

By: Javier Encinas, PE | February 13, 2019The design of anchor rods has become complex and cumbersome with the development of the ACI 318 anchorage 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 blog post is an overview of the required checks in the design of anchor rods.Multiple checks need to be done for several failure modes, which in turn depend on the geometry of the concrete support. The anchor rods in a typical column are usually subjected to a combination of tension and shear forces. The ACI treats separately tension [...]

How to Design Uplift Footings Using ASDIP FOUNDATION

By: Javier Encinas, PE | January 31, 2019ASDIP FOUNDATION is a structural engineering software for the design of concrete footings. It includes the design of uplift footings, based on the ACI 318 provisions. This document covers the design of footings subject to uplift loading using ASDIP FOUNDATION.Uplift loads may be applied to a footing for a number of reasons, but the most common uplift loads are due to wind. For example a light warehouse building in a hurricane zone can be exposed to this kind of uplift loading. In such cases, the gravity forces due to footing selfweight, pedestal and [...]

Biaxial Column Design Example Using ASDIP CONCRETE

By: Javier Encinas, PE | January 8, 2019 ASDIP CONCRETE is a structural engineering software for the design of concrete members. It includes the design of biaxial columns based on the ACI 318 provisions. This document is a step-by-step design example of a biaxial slender column using ASDIP CONCRETE. As an example, consider the 20 ft long non-sway square column shown below, which is part of an office building. The lateral loads will be resisted by shear walls, but the columns will have wind end moments due to deformation compatibility. Design the column reinforcement for the loads shown. Amplify the [...]

Counterfort Retaining Wall Design Example Using ASDIP RETAIN

By: Javier Encinas, PE | December 5, 2018 ASDIP RETAIN is a structural engineering software for the design of retaining walls. It includes the design of counterfort retaining walls based on the IBC / ACI 318 provisions. This document is a step-by-step design example of a typical counterfort retaining wall using ASDIP RETAIN.As an example, consider the retaining wall shown below, which supports a flat backfill load. Due to the wall height of 25 feet, the use of counterforts has proven itself to be a more economical solution. The soil bearing capacity is 4 ksf. The backfill density is 115 pcf [...]

Combined Footing Real-Life Example Using ASDIP FOUNDATION

By: Javier Encinas, PE | November 13, 2018 ASDIP FOUNDATION is a structural engineering software for the design of concrete footings. It includes the design of combined footings, based on the ACI 318 provisions. This document is a step-by-step design example of a real-life combined footing using ASDIP FOUNDATION. As an example, consider the combined footing shown below, which is part of the foundation of a pipe rack in an industrial plant. A typical bent consists of two steel columns closely spaced that share the same footing. The pipe rack is exposed to dead, live, and wind loads, whose reactions [...]

Beam to Girder Connection Real-Life Example Using ASDIP STEEL

Spread Footing Real-Life Example Using ASDIP FOUNDATION

By: Javier Encinas, PE | October 15, 2018 ASDIP FOUNDATION is a structural engineering software for the design of concrete footings. It includes the design of biaxial spread footings, based on the ACI 318 provisions. This document is a step-by-step design example of a real-life spread footing using ASDIP FOUNDATION. As an example, consider the spread footing shown below, which is part of a building expansion. The new footing is adjacent to an existing footing, and the dimensions are also affected by the proximity of the property limit. As a result, the column will be eccentric in both directions. Design [...]

Composite Beam Design Example Using ASDIP STEEL

By: Javier Encinas, PE | Aug 22, 2018 ASDIP STEEL is a structural engineering software for the design of structural steel members. It includes the design of composite beams based on the AISC provisions. This document is a step-by-step design example of a composite beam using ASDIP STEEL. As an example, consider the beam shown below, which is part of a storage building. The first level is a parking space, therefore the second floor will have a series of transfer beams to support the columns of the storage levels above, which typically are in a 10'x10' grid. Design the transfer [...]

Retaining Wall on Piles Design Example Using ASDIP RETAIN

Insert Image By: Javier Encinas, PE | July 4, 2018 ASDIP RETAIN is a structural engineering software for the design of retaining walls. It includes the design of cantilever retaining walls supported on piles based on the IBC / ACI 318 provisions. This document is a step-by-step design example of a typical retaining wall on piles using ASDIP RETAIN. As an example, consider the retaining wall shown below, which is part of an access ramp in a parking garage building. Due to the poor soil conditions, the soils report has recommended the use of steel piles HP12x53, with the shown [...]

Retaining Walls Supported on Piles: A Design Overview

By: Javier Encinas, PE | May 22, 2018 A retaining wall is a structure exposed to lateral pressures from the retained soil plus any other surcharges and external loads. When the wall is founded on soil, all overall stability failure modes need to be checked. But what about when the wall is supported on piles? This article discusses the design steps in the design of retaining walls supported on piles. Our software ASDIP RETAIN will be used to support the discussion. What are the loads transferred to the foundation? In addition to [...]
