同样是 7 度设防，钢构厂房的震后表现往往好于砖混建筑，秘密在于延性与自重这两个指标。Under the same seismic intensity, steel plants consistently outperform masonry buildings. The secret: ductility and low self-weight.
很多客户来自地震多发区，比如菲律宾、智利、印尼。评估结构抗震能力，关键看两个指标：延性和自重。
钢材的延性好，构件可以通过塑性变形耗散地震能量，而不是脆性断裂；钢构自重仅为混凝土结构的 30% 左右，地震作用本身与自重成正比——房子越轻，地震「推」它的力就越小。
设计层面，我们会按项目所在国的设防烈度确定地震作用，并通过强柱弱梁、节点验算保证结构「坏而不倒」。如果您在多震区建厂，报价时请务必告诉我们当地设防参数，这直接影响用钢量与节点设计。
Many of our clients build in seismic regions — the Philippines, Chile, Indonesia. Two parameters decide how a structure behaves: ductility and self-weight.
Steel is ductile: members dissipate seismic energy through plastic deformation instead of brittle failure. And steel weighs only about 30% of a concrete structure — seismic force is proportional to mass, so a lighter building is pushed less.
In design we apply the seismic intensity of the project's country, and use strong-column/weak-beam principles plus joint verification to ensure the structure deforms but does not collapse. If your plant is in a seismic zone, always tell us the local design parameters — they directly affect tonnage and joint design.
