Question

question 3 minimum design loads for buildings and other structures can be found through calculations in building codes in structures textbooks through testing

Explanation:

Building codes typically specify minimum design loads for buildings and other structures. Structures textbooks also cover such fundamental design - related information. Calculations are used to apply these loads, and testing is for validating structural performance under loads, not for finding the minimum design loads themselves.

Answer:

B. in Building Codes, C. in structures textbooks
