Observations

In the computer programs Rt and Rts we create objects for Models and Methods. The Methods are algorithms that solve well-defined problems, such as linear systems of equations, addressed elsewhere on this website. In contrast, the Models, and the numbers we input to them, can be more challenging because we want to represent “real world” hazards, material behaviour, costs, etc. What is the intensity of future earthquakes at the building site? What will the strength of a load-bearing wall be? What is the environmental impact of extracting and manufacturing the construction materials? What discount rates should we use? What is the uncertainty associated with the predictions? This page is an attempt at addressing such problems for Vancouver.
