Description
技术领域technical field
本发明涉及一种摩擦-软钢复合阻尼器及装配方法，属于土木工程结构消能减震技术领域。The invention relates to a friction-mild steel composite damper and an assembly method thereof, belonging to the technical field of energy dissipation and shock absorption of civil engineering structures.
背景技术Background technique
工程结构消能减震技术是利用消能装置能够耗散或吸收地震作用能量的特点，在结构的某些部位设置消能减震装置，以减少主体结构的地震反应，达到消能减震的目的。耗能减震技术具有减震机理明确、耗能效果明显、适应性强及维护方便等特点，目前已有的耗能器和阻尼器主要包括摩擦耗能器、粘弹性阻尼器、粘滞阻尼器、软钢阻尼器、铅挤压阻尼器和记忆合金阻尼器等。其中摩擦阻尼器具有较好的库仑阻尼特性，构造简单、适应性强、制作成本相对低，但所期望的摩擦系数会随着时间与荷载循环次数的增大而减小。软钢阻尼器充分利用了软钢材料较好的屈服后性能，以及进入塑性后良好的滞回特性，达到明显的耗能效果。但软钢阻尼器的可恢复性差，滞回环可能因为形状制作不当而发生畸变。其他类型阻尼器也都具有相应的优缺点，特别是耗能机制单一，实际工程应用中都存在局限性。因此，若能同时利用两种或以上的耗能机制，以克服单一性的缺点，所制作的阻尼器将更适合于工程推广应用。The energy dissipation and shock absorption technology of engineering structures is to use the characteristics of energy dissipation devices that can dissipate or absorb earthquake energy, and install energy dissipation and shock absorption devices in certain parts of the structure to reduce the seismic response of the main structure and achieve the effect of energy dissipation and shock absorption. Purpose. Energy dissipation shock absorption technology has the characteristics of clear shock absorption mechanism, obvious energy dissipation effect, strong adaptability and convenient maintenance. Currently, the existing energy dissipation devices and dampers mainly include friction energy dissipation devices, viscoelastic dampers, and viscous dampers. damper, mild steel damper, lead extrusion damper and memory alloy damper, etc. Among them, the friction damper has good Coulomb damping characteristics, simple structure, strong adaptability, and relatively low manufacturing cost, but the expected friction coefficient will decrease with the increase of time and the number of load cycles. The mild steel damper makes full use of the good post-yield performance of the mild steel material and the good hysteresis characteristics after entering the plasticity to achieve an obvious energy dissipation effect. However, the recoverability of the mild steel damper is poor, and the hysteresis loop may be distorted due to improper shape fabrication. Other types of dampers also have corresponding advantages and disadvantages, especially the single energy dissipation mechanism, which has limitations in practical engineering applications. Therefore, if two or more energy dissipation mechanisms can be utilized at the same time to overcome the shortcoming of singleness, the manufactured damper will be more suitable for engineering popularization and application.

本实施例中，所述顶板、底板、摩擦斜腹杆、第一至第三套管材料采用Q345，所述第一至第三软钢直杆材料采用宝钢BLY160。In this embodiment, Q345 is used for the top plate, bottom plate, friction diagonal rod, and the first to third casings, and Baosteel BLY160 is used for the first to third mild steel straight rods.
在未发生地震的正常使用阶段时，静摩擦力与软钢直杆的拉力共同提供承载力，当荷载超过一定限制时，结构发生变形，摩擦面A与摩擦面a、摩擦面B与摩擦面b分别产生相对位移与摩擦力，通过摩擦耗能消散一定的地震作用；同时，由于摩擦斜腹杆成八字形向两边滑动，固定于摩擦斜腹杆间的软杆直杆受拉进入弹塑性变形阶段，通过往复滞回变形消耗地震作用于结构的振动能量。In the normal use stage without earthquakes, the static friction force and the tensile force of the mild steel straight rod jointly provide the bearing capacity. When the load exceeds a certain limit, the structure deforms, and the friction surface A and the friction surface a, and the friction surface B and the friction surface b Relative displacement and friction force are generated respectively, and a certain amount of seismic action is dissipated through frictional energy dissipation; at the same time, since the friction diagonal rods slide to both sides in a figure-eight shape, the soft straight rods fixed between the friction diagonal rods are pulled into elastic-plastic deformation stage, the vibration energy of the earthquake acting on the structure is consumed through reciprocating hysteretic deformation.
