Load Combinations

Load combinations are scenarios engineers use to ensure structures like buildings or bridges can safely withstand various force combinations they might face. Since structures experience different loads—such as weight, wind, or seismic activity—load combinations account for how these forces might occur together. Engineers calculate these combinations using specific rules to test the structure’s strength and stability under possible real-world conditions, ensuring safety and durability without overdesigning or wasting resources. Essentially, load combinations help predict the worst-case scenarios a structure must handle throughout its lifespan.
