Initial Sizing & Hand Calcs Training
Initial Sizing & Hand Calcs Training Course Description
This intensive, two-day Initial Sizing & Hand Calcs Training provides the attendee with directly applicable tools to get their jobs done. The emphasis is on tactical execution of structural sizing during the initial phases of a design to ensure the concepts will meet the requirements when more thorough analysis is completed later. The methods are all presented as functions to aid the attendee in understanding the influence of the various design parameters that drive sizing of the structure. In additional to the presentation and equations, digital copies of references are provided with Excel and MathCAD versions of the solutions provided to allow implementation of the methods immediately. Each topic presented could be extended to one or more days of training. In fact, some topics are routinely given as multi-day sessions. This course is not like that and instead provides an 80/20 rule solution for most configurations seen in production and then provides the resources for the designer and analyst to investigate further as required. By emphasizing fast, accurate, and easy to understand sizing rules, designs are set on the correct trajectory early in the development phase thereby reducing or eliminating the need for costly redesigns later. Worked examples and hands-on class problems are presented.
With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.
