鋼筋(Reinforcing Steel Bar) 是土木工程中用于增強混凝土結構強度的關鍵材料,通常簡稱螺紋鋼 或rebar。其核心作用是通過與混凝土協同工作,彌補混凝土抗拉強度低的缺陷,提升建築構件的整體承載力和抗震性能。
鋼筋是一種表面帶有橫肋或縱肋 的碳素鋼長條(少數采用合金鋼),通過機械軋制或冷加工成型。其肋紋設計可顯著增強與混凝土的粘結強度,防止受力時發生滑移。标準鋼筋需符合嚴格的力學性能指标,如屈服強度(常見等級為 HRB400、HRB500)和延展性,确保結構在荷載下安全變形而非脆性斷裂。
混凝土抗壓強度高但抗拉強度弱,鋼筋則提供抗拉補強。例如在梁構件中,鋼筋布置于受拉區,承擔拉力;在柱體中則通過箍筋約束混凝土,提高抗壓韌性。這種組合使鋼筋混凝土成為現代建築的基石,廣泛應用于房屋、橋梁、隧道等工程。
全球主要标準包括:
鋼筋按直徑分級(如 Ø6mm–Ø50mm),通過綁紮或焊接形成骨架後澆築混凝土,用于:

"Reinforcing steel bar"(簡稱rebar)是建築工程中的專業術語,具體含義和用法如下:
指用于增強混凝土結構強度的鋼制條狀材料,通常表面帶有肋紋以提高與混凝土的黏結力。中文直譯為“鋼筋”,在工程領域常縮寫為“rebar”或“steel bar”。
在工程文件中需注意與普通鋼條(steel bar)區分,後者可能泛指任何鋼質條材,而reinforcing steel bar特指混凝土結構用鋼筋。國際标準中對其規格(如直徑、強度等級)有嚴格規定。
