Description
技术领域Technical Field
本发明涉及建筑结构耗能支撑技术领域，具体涉及一种分级屈服装配式耗能支撑。The invention relates to the technical field of building structure energy dissipation support, and in particular to a graded yielding assembled energy dissipation support.
背景技术Background technique
地震灾害对建筑结构的破坏一直以来都受到人们的广泛关注，框架结构是现阶段使用较多的一种结构形式，针对框架结构的抗震要求，现有结构常见的做法是在框架柱之间设置防屈曲支撑，在小震情况下，防屈曲支撑为结构提供附加刚度；在中震和大震情况下，防屈曲支撑在往复拉压作用下先于主体结构进入塑性状态，形成饱满的滞回曲线以耗散地震能量，从而保证整体结构的安全性和稳定性。The damage caused by earthquake disasters to building structures has always attracted widespread attention. Frame structure is a widely used structural form at this stage. In view of the seismic requirements of frame structure, the common practice of existing structures is to set anti-buckling braces between frame columns. In the case of small earthquakes, the anti-buckling braces provide additional stiffness for the structure; in the case of moderate and large earthquakes, the anti-buckling braces enter the plastic state before the main structure under the action of reciprocating tension and compression, forming a full hysteresis curve to dissipate seismic energy, thereby ensuring the safety and stability of the overall structure.
但传统的防屈曲支撑仅内芯与结构构件相连，荷载完全由内芯承担，混凝土约束外套筒和填充材料仅起着约束内芯板受压屈曲，以防止内芯板受压失稳的作用，即仅考虑内芯一个耗能核心，不考虑外套约束筒的轴向刚度贡献，导致内芯在地震中可能过早失去作用。另外，混凝土约束存在湿作业工作量大、不利于环保、无法观察核心部件的损伤情况等缺陷，为了替代混凝土约束，目前比较认可的是采用全钢约束型构件，但支撑段都采用钢板约束造成了钢材用量增加，导致支撑构件造价增加。However, the traditional buckling-resistance brace only connects the inner core to the structural member, and the load is completely borne by the inner core. The concrete restraint outer sleeve and filling materials only play the role of restraining the inner core plate from buckling under compression to prevent the inner core plate from losing stability under compression. That is, only the inner core is considered as an energy-consuming core, and the axial stiffness contribution of the outer restraint sleeve is not considered, which may cause the inner core to lose its function prematurely in an earthquake. In addition, concrete restraint has defects such as large wet work workload, environmental protection, and inability to observe the damage of core components. In order to replace concrete restraint, the currently more recognized method is to use all-steel restraint components, but the support sections are all restrained by steel plates, which increases the use of steel and increases the cost of support components.
针对上述问题，本发明提供一种轴向变形和轴向刚度可控，造价较低，方便施工、损伤检测及修复更换的分级屈服装配式耗能支撑。In view of the above problems, the present invention provides a graded yield assembled energy dissipation support with controllable axial deformation and axial stiffness, low cost, and convenient construction, damage detection, and repair and replacement.

贴附在所述耗能钢2外侧的附加翼缘板4；An additional flange plate 4 attached to the outer side of the energy dissipation steel 2;
连接两外侧所述附加翼缘板4的加劲肋5；以及A stiffening rib 5 connecting the two outer additional flange plates 4; and
固接在所述附加翼缘板4端部和加劲肋5外端面的端板6。An end plate 6 is fixedly connected to the end of the additional flange plate 4 and the outer end surface of the stiffening rib 5.
若干个所述耗能钢2成排分布在传力H型钢1端部腹板的两侧边。A plurality of energy-absorbing steels 2 are distributed in rows on both sides of the web at the end of the force-transmitting H-shaped steel 1 .
所述附加翼缘板4连接同排侧的所有耗能钢2，使得同排侧的耗能钢2连为一个整体，以便于将端板6上的力同时传递给整排的耗能钢2。The additional flange plate 4 connects all the energy-absorbing steels 2 on the same row side, so that the energy-absorbing steels 2 on the same row side are connected as a whole, so as to simultaneously transmit the force on the end plate 6 to the energy-absorbing steels 2 of the entire row.
所述耗能钢2与传力H型钢1的端部腹板、附加翼缘板4之间均通过螺栓连接。The energy-absorbing steel 2 is connected to the end web plate and the additional flange plate 4 of the force-transmitting H-shaped steel 1 by bolts.

所述端板6与附加翼缘板4、加劲肋5之间均通过焊接方式连接。The end plate 6 is connected to the additional flange plate 4 and the stiffening rib 5 by welding.
所述耗能钢2为耗能方钢或耗能环形钢，如图6所示，根据实际耗能需求调节耗能钢2的数量，根据刚度需求调节耗能板3的数量和位置。The energy-absorbing steel 2 is energy-absorbing square steel or energy-absorbing ring steel, as shown in FIG6 . The quantity of the energy-absorbing steel 2 is adjusted according to the actual energy-absorbing demand, and the quantity and position of the energy-absorbing plates 3 are adjusted according to the stiffness demand.
本发明连接过程及原理Connection process and principle of the present invention
本发明中，先依次将一块加劲肋5、两块附加翼缘板4焊接在同一块端板6上，然后将耗能板3焊接在部分耗能钢2内部，并将所有耗能钢2通过高强螺栓并排连接在传力H型钢1两端的腹板上，最后将已经与加劲肋5、端板6焊接于一体的附加翼缘板4通过高强螺栓连接到耗能钢2外侧。In the present invention, a stiffening rib 5 and two additional flange plates 4 are welded to the same end plate 6 in sequence, and then the energy dissipation plate 3 is welded inside a part of the energy dissipation steel 2, and all the energy dissipation steels 2 are connected side by side to the webs at both ends of the force transmission H-shaped steel 1 through high-strength bolts, and finally the additional flange plate 4 that has been welded to the stiffening rib 5 and the end plate 6 is connected to the outside of the energy dissipation steel 2 through high-strength bolts.
继续参照图1至图5，当构件承受轴向力时，力依次通过端板6、附加翼缘板4、耗能钢2传递到传力H型钢1，其中耗能钢2因两边受力方向相反壁板发生弯曲变形，而耗能钢2内的耗能板3率先进入塑性耗能，当变形达到一定程度时，耗能钢2发生屈服，这样，在往复轴力作用下，耗能板3和耗能钢2可通过进入塑性达到消耗能量的目的，另外，当该耗能支撑需要提供较大的轴向承载力和轴向刚度时，可通过增加耗能钢2和耗能板3的数量以及调节耗能板3的位置等方式来增大耗能支撑的刚度、承载力以及耗能能力，这样即可实现耗能支撑轴向承载力和轴向变形可控目的。Continuing to refer to Figures 1 to 5, when the component is subjected to axial force, the force is transmitted to the force-transmitting H-shaped steel 1 through the end plate 6, the additional flange plate 4, and the energy-absorbing steel 2 in sequence, wherein the energy-absorbing steel 2 is bent and deformed due to the opposite force directions on both sides of the wall plate, and the energy-absorbing plate 3 in the energy-absorbing steel 2 is the first to enter plastic energy consumption. When the deformation reaches a certain degree, the energy-absorbing steel 2 yields. In this way, under the action of reciprocating axial force, the energy-absorbing plate 3 and the energy-absorbing steel 2 can achieve the purpose of consuming energy by entering plasticity. In addition, when the energy-absorbing support needs to provide a larger axial bearing capacity and axial stiffness, the stiffness, bearing capacity and energy-absorbing capacity of the energy-absorbing support can be increased by increasing the number of energy-absorbing steel 2 and energy-absorbing plates 3 and adjusting the position of the energy-absorbing plates 3. In this way, the purpose of controllable axial bearing capacity and axial deformation of the energy-absorbing support can be achieved.
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
