Steel does not burn – but high temperatures significantly influence its structural behavior. As the temperature increases, steel gradually loses both strength and stiffness. By approximately 600°C, structural steel retains only about 50% of its yield strength, a benchmark referenced in major design standards such as Eurocode and AISC. Importantly, steel does not need to reach its melting point to compromise a structure. Well below that temperature, the material softens
Rigid frame Pre-Engineered Buildings (PEB) can be designed to support 𝐄𝐎𝐓 𝐜𝐫𝐚𝐧𝐞 𝐬𝐲𝐬𝐭𝐞𝐦𝐬 𝐮𝐩 𝐭𝐨 𝟏𝟓 𝐌𝐓 (span up to 21 m), in compliance with 𝐀𝐈𝐒𝐂 𝐚𝐧𝐝 𝐌𝐁𝐌𝐀 𝐬𝐭𝐚𝐧𝐝𝐚𝐫𝐝𝐬. For crane-supported buildings, structural performance goes beyond static loads – dynamic effects must be carefully evaluated. Typical design considerations include: Bracket-mounted crane runway systems Independent support columns for higher crane capacities Impact allowance of 10–25% of the maximum wheel load 20% lateral force from trolley movement Verification of critical load combinations Crane buildings are dynamic systems.
