Independent Technical Review

A truly independent technical should not require access to the designers notes and decision making process, and thus should not require any submission of calculations. An independent review should only require access to the specification-of-intent. With a complete specification, it should be possible to send it to the other side of the world and get […]

Doubly Pitched, Gable Roof Structures, enclosed buildings and canopies.

Introduction Simple doubly pitched roof. Two structural members and three joints, with two of the joints as supports. The basic connection options for joints is pinned that is having no moment restraint, or fully fixed in which case has moment restraint. If have moment restraint then joint can resist forces which tend to cause rotation […]

Software to Automate Engineering for Structural Products

Given an idealistic view that engineering takes place at the frontiers of science and technology, no engineering should be required for structural products as they are largely established technologies. However there may be need to make prototypes and physically test them to get some empirical data, and calibrate mathematical models. Additionally there are issues of […]

Manufactured Structural Product – Some Useful Terminology

Terminology Structural Product:  A system, a component of a system or an application. System: a collection of components which can be combined to create an assembly suitable for a specific application. Application: an assembly produced from the structural system for a specific purpose. Installation: a given application installed on a specific site to meet an […]

Manufactured Structural Product – A Start to Defining

A manufactured structural product (MSP), is a product that is dependent on structural engineering/design to demonstrate its fitness-for-function, and is otherwise fabricated in a factory and then transported to site and assembled. Primarily the intent is that it is designed once and fabricated and installed many times. The reality is, that the structural product is […]

Plane Frame (2D) Matrix Structural Analysis

Now have source code for 2D Plane frame matrix structural analysis in Turbo Pascal, Delphi 3, Lazarus and Excel/vba using arrays indexed from base 1. Additionally have source Excel/vba, JavaScript/JScript, VB.net, C# and Java using arrays indexed from base zero. Was going to use J# as an intermediate step between C# and Java, but not […]

Canopy Design: pt#1 (Basic Procedure)

Free standing canopy (carports etc..) design is similar to the requirements for shed design. The primary difference is that with no wall cladding the wind load pushing against the side of the canopy is less. There is still a side ways load on the canopy, it comes from the horizontal component of the loads on […]

Shed Design: pt#1 (Basic Procedure)

The basic procedure for shed design involves assessing the loads imposed by the environment, determining the effects of those loads on the frame and its connections and then specifying such so that have adequate resistance. {what follows is a rough outline and subject to revision.} Environmental Assessment Environmental considerations include, rain, flood waters, hail, snow, […]

Certificates of Independent Technical Expert

WARNING: You cannot legitimately get a Certificate of an Independent Technical Expert (Regulation 88), unless you already have engineering/technical calculations or some other form of certification (or documented evidence-of-suitability). Also note that the South Australian Development Application fees typically cover the cost of council sending engineering design out for review and certification by an independent […]
