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, [...]

Footing Design: How to Check the Shear Capacity per ACI 318

By: Javier Encinas, PE | August 14, 2017 The foundation is that part of the structure that transfers the loads to the supporting soil in such a way that the resulting bearing pressures are kept under acceptable limits. If the underlying soil is satisfactory, then a spread footing is usually the recommended solution by the soils engineer. In addition to the stability checks and the design for flexure, a spread footing needs to be designed for shear. This blog post discusses the shear checks required by ACI 318. Our software ASDIP FOUNDATION will be used to support our discussion. What [...]

Cantilever Retaining Walls: How to Calculate the Bearing Pressure

By: Javier Encinas, PE | July 25, 2017 A retaining wall is a structure exposed to lateral pressures from the retained soil plus any other surcharges and external loads. All overall stability failure modes must be thoroughly checked, including the bearing capacity of the supporting soil. This article discusses the calculation of the soil bearing bearing pressures under cantilever retaining walls. Our software ASDIP RETAIN will be used to support the discussion. What are the typical loads on a retaining wall? In addition to the retained backfill, retaining walls may be subject to surcharge loads at the top [...]

How to Design Spread Footings Using ASDIP FOUNDATION

By: Javier Encinas, PE | July 12, 2017 ASDIP FOUNDATION is a structural engineering software for design of concrete footings. It includes the design of spread footings based on the latest ACI provisions. Following is a graphical overview of the required design steps, with annotated screenshots of the software. Click To Enlarge Enter the footing dimensions in plan and elevation view. Specify the soil cover and the water table depth. Click on the Column tab and specify the column dimensions. The column can be offset in both directions. If column is a short pedestal, loads [...]

Combined Footings: How to Calculate the Bearing Pressures

By: Javier Encinas, PE | June 27, 2017 ASDIP FOUNDATION includes the design of concrete combined 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 combined footing. A combined footing usually supports two columns. The use of a combined footing may be justifiable under conditions where the distance between columns is short, so a large excavation is not required. There are two common scenarios in practice: A property line exists at or near the edge of an exterior column, so a normal isolated footing [...]

Anchor Rods: How to Calculate the Tension Breakout Capacity

By: Javier Encinas, PE | June 14, 2017 Anchor rods are elements designed to resist mostly tension forces, sometimes in combination with shear. Out of all the tension limit states required by ACI 318, concrete breakout is particularly important because a concrete failure would be non-ductile, and therefore it should be avoided. This blog post discusses how to calculate the breakout capacity of anchor rods. I will use our software ASDIP STEEL to support the discussion. Concrete breakout assumes a failure forming a concrete cone based on a prism angle of 35 degrees. This method predicts the strength [...]

How to Design Steel and Composite Beams Using ASDIP STEEL

By: Javier Encinas, PE | May 31, 2017 ASDIP STEEL is a structural engineering software for design of steel members. ASDIP STEEL software includes the design of steel and composite beams based on the AISC 360 provisions. Following is an overview of the required steps to design steel and composite beams using ASDIP STEEL. Click To Enlarge This structural engineering software has a built-in database of the AISC steel sections. Enter the span dimensions and properties in the Steel Beam tab. Specify the location of the lateral bracing points. Specify whether the supports [...]

How to Design Restrained Retaining Walls Using ASDIP RETAIN

By: Javier Encinas, PE | May 22, 2017 ASDIP RETAIN is a structural engineering software for design of retaining walls. ASDIP RETAIN software includes the design of either concrete or masonry top-restrained retaining walls based on the latest ACI 318 and MSJC provisions. 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. [...]
