On Products and Descriptions

The products described on this site represent products primarily of use to manufacturers of structural products (MSP’s). These products can have either a fixed form or a variable form.  A manufacturer/supplier asking for calculations for council for a specific sized building is only appropriate if the product has fixed form and their customer cannot make […]

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 […]

Stairs: Compatibility with AS1657 and BCA

Created a simple spreadsheet which permits a semi-graphical approach to finding a suitable rise and run (going) for a staircase. Since the Building Code of Australia (BCA) and referenced fixed standard AS1657: platforms, walkways, stairways and ladders, have different criteria for acceptability of a stairway the first step was to graphically see the difference. For […]

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.} [toc] Environmental Assessment Environmental considerations include, rain, flood waters, hail, […]
