INTRODUCTION This guide is written to assist you (manufacturers/suppliers) with the following: Guidance on what services a consulting engineer can offer and therefore enable you to obtain the most appropriate service for your needs. Guidance on the risk, liability and responsibilities that engineering practitioners usually accept in the course of their duties. THE GUIDE Users […]


INTRODUCTION What follows is a simplified method of design and estimating of structural adequacy for use by shed fabricators/suppliers and other manufacturers/suppliers whose products are based on pre-engineered solutions. These enterprises either have existing products that have a history of successful operation, or a range of products that have been demonstrated to be compliant with […]

Design Wind Speeds for South Australia

BASIC REGIONAL WIND SPEED Typical Building/Structure V[R] = 45 m/s [162 km/h] mean return period 500 years 5% risk of exceedance for 25 year design life Post Disaster Building/Structure V[R] = 48 m/s [173 km/h] mean return period 2000 years 1.25% risk of exceedance for 25 year design life These wind speeds are typically as […]

Setting Up Spreadsheet Environment

General instructions for setting up environment for use of my spreadsheet collection, either downloaded from here or from ExcelCalcs. To test the installation, I create a new limited user account on MS Windows. I have done this previously for Windows XP, and Windows 7. The current process was on Windows 10, which is an upgrade of […]

Ten Types of Spreadsheet or eWorkBook Applications

TYPE 1: Reference Library These eWorkBooks are databases or tables of data which are largely constant, and used as lookup values for calculations. They include such things as materials libraries, properties of chemical elements and such things. {MS Access or other DBMS potentially the better tool for this} TYPE 2: Data Collection These are eWorkBooks […]

Coffee with STEAM

When first read about coffee with an architect, it seemed like a good idea, and something similar would be good for engineering, such as an equivalent coffee with an engineer.  However, being classified by Engineers Australia as an engineering technologist, it becomes a more cumbersome phrase.  Personally I don’t care much for occupational classification, it […]

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 […]

Example Canopy Design and Documentation: Carports, Verandahs and Pergolas

Typically our involvement with carports, verandahs and pergolas, or more generally canopies, is the supply of structural reports or certification. Both reports and certification involve structural calculations. The difference between the report and certification is that we don’t compile the calculations into a report and issue the calculations. Instead with certification we summarise critical values […]

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 […]
