以受弯为主的主梁作为承重构件的桥梁。主梁可以是实腹梁或桁架梁。实腹梁构造简单，制造、架设和维修均较方便，广泛用于中、小跨度桥梁，但在材料利用上不够经济。桁架梁的杆件承受轴向力，材料能充分利用，自重较轻，跨越能力大，多用于建造大跨度桥梁。按照主梁的静力体系，分为简支梁桥、连续梁桥和悬臂梁桥。①简支梁桥。主梁以孔为单元，两端设有支座，是静定结构。一般适用于中、小跨度，结构简单，制造、运输和架设均甚方便，多做成标准设计，以便于构件生产工艺工业化、施工机械化，提高质量，降低造价。如洛阳黄河桥（67孔跨径50米，全长3429米，1977年建成）。郑州黄河桥（28孔跨径20米、62孔跨径50米、47孔跨径40米，全长5550米，1986年建成）、开封黄河桥（31孔跨径20米、77孔跨径50米，全长4475米，1989年建成）均为公路预应力混凝土T形简支梁桥。②连续梁桥。主梁若干孔为一联，连续支承在几个支座上，是超静定结构。当跨度较大时，采用连续梁较省材料，更适合用悬臂拼装或悬臂灌筑、纵向拖拉或顶推法施工。如京石公路永定河桥，为预应力混凝土箱形连续梁，1988年建成；武汉长江桥、南京长江桥为钢桁架连续梁桥。③悬臂梁桥。上部结构由锚固孔、悬臂和悬挂孔组成，悬挂孔支承在悬臂上，用铰相联。有单悬臂梁桥（三跨构成，中跨较大以满足通航要求）和双悬臂梁桥（可构成多跨的长大梁桥）。如陕西省咸阳渭河桥（主跨174米，全长448米，1954年建成)为钢筋混凝土悬臂梁桥。梁桥为桥梁的基本体系之一，使用广泛，在桥梁建筑中占有很大比例，其上部结构可以是木结构、钢结构、钢筋混凝土结构、预应力混凝土结构或钢筋混凝土桥面板和钢梁的组合结构。
