Following is an overview of the steps required to design basement retaining walls using ASDIP RETAIN. Click To Enlarge Select the stem material, either concrete or masonry. ASDIP RETAIN will adjust the input fields. Enter the wall and footing dimensions in the Geometry tab. Wall can be modeled as either pinned or [...]

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 [...]

How Are the Calculations Managed in ASDIP Software?

By: Javier Encinas, PE | May 8, 2017 ASDIP is a structural engineering software for the design of structural members and components, capable to create complex calculations. But how exactly does ASDIP manage all these calculation sets in a project? This blog post discusses this important part of the software. Structural engineering is all about calculations, and even a simple project may contain several sets of calculations for different members. The Project Manager is the central piece of ASDIP software. It is in charge of organizing all the calculations in a project, and keeping the common information updated and active. [...]

How to Design a Fence Wall Using ASDIP RETAIN

By: Javier Encinas, PE | May 2, 2017 ASDIP RETAIN is a structural engineering software to design retaining walls. However, the software is so flexible that it can also be used to design a masonry fence wall exposed to wind. This article shows the steps required to design a fence wall using ASDIP RETAIN. Click To Enlarge As an example, let's design a typical fence 7'-0" high exposed to a wind load of 20 psf. The first obvious step in the software is to set the backfill height to match the soil cover at [...]

Can Anchor Rods Resist High Shear Loads?

By: Javier Encinas, PE | April 26, 2017 During a recent technical support session a customer asked how effective the anchor rods are, as compared to shear lugs, to resist high shear loads. The obvious answer was that shear lugs are by far more effective. Rather than arguing with theories, I decided to quantify the answer by testing, using our software ASDIP STEEL. This document reports my findings. For this experiment, I selected a 18"x 18" base plate supported on a 24"x 24" pedestal, which are very common sizes. The column will transfer the factored loads shown below [...]

Strap Footings: How to Calculate the Bearing Pressures

By: Javier Encinas, PE | April 16, 2017 ASDIP FOUNDATION includes the design of concrete strap footings. This structural engineering software is based on the latest ACI 318 provisions. This post explains the calculation of the soil bearing pressures in a typical strap footing. 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 problem may be prevented by connecting this footing with [...]

How to Design Out-of-Plane Bearing Walls Using ASDIP CONCRETE

By: Javier Encinas, PE | April 10, 2017 ASDIP CONCRETE is a structural engineering software for design of concrete members. It includes the design of out-of-plane bearing walls based on the latest ACI 318 provisions. Following is a visual overview of the steps required to design this type of concrete walls using ASDIP CONCRETE. Click To Enlarge Enter the wall thickness in the Geometry tab. Specify the reinforcement size and spacing. Enter the unsupported height and condition at top. ASDIP CONCRETE generates an At-a-Glance presentation of results, organized by topic. [...]

Shear Lug Design: Overview of the ACI Provisions

By: Javier Encinas, PE | April 4, 2017 Shear lugs are steel elements welded to the underside of base plates to resist shear loads. The design of shear lugs is covered by the ACI 349 anchorage provisions. This post is an overview of the structural design process. Our software ASDIP STEEL will be used to support our discussion. How do you calculate the shear force in a shear lug? The lateral forces acting on a structure will produce a horizontal reaction at the foundation level. For steel frames supported on base plates, a small horizontal force can be resisted by the [...]

Steel / Composite Beams: Optimizing the Design with ASDIP STEEL

By: Javier Encinas, PE | March 27, 2017 Beams are structural elements that support loads applied transversely, which produce a combination of shear and bending stresses. The structural design of steel beams includes the check of multiple limit states for both shear and bending. For composite beams, it’s important to consider the loads that will be applied before and after the composite action takes place. In the pre-composite stage, the flexural behavior of a steel beam is a function of the unbraced length Lb for the limit state of lateral-torsional buckling. In a composite beam, shear connectors are usually provided to transfer [...]

Cantilever Retaining Walls: How to Calculate the Sliding Safety Factor

By: Javier Encinas, PE | March 13, 2017 Retaining walls are structures designed to bound soils between two different elevations, therefore they are mainly exposed to lateral pressures from the retained soil plus any other surcharge. Cantilever walls may be sensitive to sliding problems, particularly if founded on poor soils. This article discusses the sliding calculations in either concrete or masonry cantilever retaining walls. Our software ASDIP RETAIN will be used to support the discussion. What are the pressures acting on a retaining wall? In addition to the retained backfill, retaining walls may be subject to surcharge loads at [...]
