摘要
提出了一种带腋撑的新型钢筋混凝土(含预应力混凝土)框架结构。该结构由常规的钢筋混凝土框架结构以及设置在节点区的腋撑组成。腋撑的设置,改变了框架梁端、框架柱端的设计控制截面的位置,大幅度减少了框架梁端、框架柱端设计控制截面的弯矩值、剪力值。结果表明,钢筋混凝土带腋撑框架结构在荷载作用下,首先在梁腋撑处的外侧形成塑性铰,然后在梁跨中出现塑性铰,且梁端及节点区受力性能良好,使得结构具有良好的承载能力和变形能力。
A new kind of reinforced concrete （including prestressed concrete） frame structure with diagonal member is put forward. The structure is composed by conventional reinforced concrete frame structure and diagonal members which are set up at the joints. It can be changed the position of the design controlling sections at the end of the frame beam and column as the diagonal member are set. In addition, the bending moment and the shearing force of the controlling sections are greatly reduced. The results of the experiment show that the first plastic hinge appears at the position of the beam-diagonal member joint, and then appears at the middle span of the beam, the end of the beam and the beam column joint have a good performance, and with a reasonable design the newly structure will have a good bearing and deformation capacity.
