补充资料：初期生铁结构
初期生铁结构
以金属作为建筑材料，早在古代建筑中就已开始，而大量的应用，特别是以钢铁作为建筑结构的主要材料则始于近代。随着铸铁业的兴起，1775~1779年第一座生铁桥（设计人：Abraham Darby）在英国塞文河上建造起来，1793~1796年在伦敦又出现了更新式的单跨拱桥——桑德兰桥，全长达236英尺（72米）。在房屋建筑上，铁最初应用于屋顶，如1786年巴黎法兰西剧院建造的铁结构屋顶（设计人：Victor Louis）以及1801年建的英国曼彻斯特的萨尔福特棉纺厂（设计人：Watt and Boulton）的七层生产车间，这里铁结构首次采用了工字形的断面。另外，为了采光的需要，铁和玻璃两种建筑材料配合应用，在十九世纪建筑中取得了巨大成就。如巴黎旧王宫的奥尔良廊（1829-1831,P.Fontaine）、第一座完全以铁架和玻璃构成的巨大建筑物——巴黎植物园的温室（1833，Rouhault），而最著名的则是1851年建造的伦敦“水晶宫”
