Question
“We are having trouble with the lab that is due this week. We know the length, width and thickness of the members which connect to U9 because we measured them. Do we use the area of the length*height in our calculations or something else? Also, do we multiply the weight by 2 because there are 2 beams per member? I was wondering about the structure of the lab too. Does a structure that has an abstract, introduction, data and calculation, and results/conclusion sound like everything we need? Thank you for your time.”
Calculations
The goal of the lab is to estimate the “dead load” on a given pier. Essentially you need to decide what members (including the bridge deck) contribute to the load on that pier. The assumption is that you’ll calculate the volume of those members using the information on the drawings as verified by your field and then calculate the weight using the information provided in the lab report on densities.
Lab Report Format and organization
Your overall format for the report is fine. I’d recommend realizing that there are seven specific tasks identified. You’ll probably help the grader, and yourselves, if you break the report down by those tasks.
