[0036] The stress constraint protection unit 3 is at least sleeved on the outer periphery of the elastic-plastic core energy-absorbing section.

[0037] Specifically, the reinforced connection section of the core energy dissipation component 2 extends outward to connect the stress restraint protection unit 3 to the building structure.

[0039] The smooth transition section is located between the reinforced connection section and the elastic-plastic core energy-absorbing section. A flexible limit block 4 is provided at the portion where the smooth transition section connects with the elastic-plastic core energy-absorbing section. The stress constraint protection unit 3 is sleeved on the outer periphery of the smooth transition section.

[0040] Specifically, the reinforced connection section and the smooth transition section are arranged in mirror image at both ends of the elastic-plastic core energy dissipation section. When the core energy dissipation component 2 undergoes elastic-plastic deformation, the flexible limit block 4 provides deformation space while limiting the deformation of the core energy dissipation component 2 beyond the design requirements.

[0041] In some embodiments, the stress constraint protection unit 3 includes a stress constraint sleeve 3-1 and a constraint filling layer 3-2, the stress constraint sleeve 3-1 is sleeved on the outer periphery of the smooth transition section and the elastic-plastic core energy absorption section, and the constraint filling layer 3-2 is filled between the stress constraint sleeve 3-1 and the outer periphery of the smooth transition section and the elastic-plastic core energy absorption section.

[0042] Specifically, the stress constraint protection unit 3 is used to ensure that the optical fiber monitoring device 7 can work normally under the elastic-plastic deformation of the energy-consuming core energy-consuming component 2.

[0043] In some embodiments, at least on the outer periphery of the elastic-plastic core energy-absorbing section where the installation chamber 6 is opened, a viscoelastic protective layer 5 is provided, and the viscoelastic protective layer 5 is provided between the constraining filling layer 3 - 2 and the elastic-plastic core energy-absorbing section.

[0044] Specifically, the viscoelastic protective layer 5 is used to protect the optical fiber monitoring device 7 .

[0045] In some embodiments, the core energy absorbing component 2 includes a core energy absorbing core material 2-1 and a reinforcing rib plate 2-2. The reinforcing connecting section, the smooth transition section and the elastic-plastic core energy absorbing section constitute the core energy absorbing core material 2-1. The reinforcing rib plate 2-2 is arranged in the reinforcing connecting section of the core energy absorbing core material 2-1.

[0046] In some embodiments, the optical fiber monitoring device 7 is installed in the installation chamber 6 in a linear manner or in a point manner.

[0047] In some embodiments, the cross section of the core energy-consuming component 2 is a straight-line structure, a cross-shaped structure, an H-shaped structure, a W-shaped structure, or a cylindrical structure.

[0048] Specifically, in some embodiments, reference Figure 2 When the cross section of the core energy-consuming component 2 is a straight-line structure, an optical fiber monitoring device 7 is provided; Figure 3 , when the cross section of the core energy dissipation component 2 is an H-shaped structure, three optical fiber monitoring devices 7 are provided; Figure 4 When the cross section of the core energy dissipation component 2 is a cross-shaped structure, two optical fiber monitoring devices 7 are provided; when the cross section of the core energy dissipation component 2 is a W-shaped structure, four optical fiber monitoring devices 7 are provided; Figure 5 When the cross section of the core energy-consuming component 2 is a cylindrical structure, two optical fiber monitoring devices 7 are provided.

[0052] The material of the viscoelastic protective layer 5 is: macromolecular viscoelastic material.

[0053] In some embodiments, the optical fiber monitoring device 7 includes a displacement sensor, a temperature sensor, and a strain sensor.

[0054] Specifically, displacement sensor: The displacement sensor usually adopts fiber Bragg grating (FBG) technology. FBG sensor can accurately measure the change of optical fiber length caused by structural deformation, so as to calculate the displacement. By arranging multiple FBG sensors at key positions of the core energy dissipation component 2, the displacement change of the entire structure can be monitored in real time.

[0055] Temperature sensor: The temperature sensor can also use FBG technology to measure temperature using the thermo-optical effect of optical fiber materials. FBG temperature sensors have the advantages of high precision, fast response and strong anti-interference ability, and can monitor the temperature changes of core energy-consuming components 2 in real time.

[0056] Strain sensor: Strain sensors also often use FBG technology to reflect the strain state of the structure by measuring the strain changes of the optical fiber. Installing FBG strain sensors at key locations of the core energy-consuming component 2 can monitor the strain distribution and changes of the structure in real time.

[0057] In summary, compared with the prior art, the optical fiber intelligent monitoring buckling restrained energy dissipation support provided by the technical solution of the above embodiment can transmit the monitoring data of energy dissipation deformation in real time through the optical fiber monitoring device, thereby effectively evaluating the working state of the buckling restrained energy dissipation support and the safety state of the building.
