Let me go through each sentence again to verify that all words are replaced except the software names. Also, check if abbreviations like ETABS and SAP2000 are handled correctly. Since the user said to skip brands and names, those stay as they are.
Starting with the first line: "Limit state design is used to design building frames, including beams, columns, and connections, to withstand various loads and stresses." Here, "used" could be replaced with applied, "design" might become construct, but wait, "design" is part of the technical name "Limit state design," so I shouldn't change that. Oops, the user said "Leave names unchanged," so "Limit state design" stays as is. So I need to be careful with technical terms. limit state design in structural steel
Also, need to handle the section headers: "Bridge Design:", "High-Rise Buildings:", "Design Steps for Limit State Design in Structural Steel," "Load Calculation:", "Material Selection:", "Section Selection." These might need some synonyms for words like "Bridge Design" – "Bridge Design" is a heading term, so maybe only change the word "Bridge" to Bridges but "Design" is part of the title. Wait, the instruction says to leave names unchanged. So maybe the entire heading "Bridge Design" should stay as is? Or is "Bridge" being modified? Need to clarify. Let me go through each sentence again to
Then: "Enhanced Durability: Limit state design helps to ensure that structures are durable and can withstand various environmental conditions, such as weathering and corrosion." Starting with the first line: "Limit state design
For the applications section: "Applications of Limit State Design in Structural Steel Limit state design is widely used in the design of structural steel buildings, bridges, and other infrastructure projects."
Another part is "evaluating the structure’s behavior" could become examining. I need to make sure the synonyms are verbs that fit the context. "Applications" might be uses.
I should make sure that each synonym set is accurate and fits the technical context. For example, "stresses" can be tensions, but "loads" is already a term in structural engineering, so using "pressures" or "tensions" is okay as long as they fit.
