The present invention relates to the technical field of energy dissipation and shock absorption buildings, and particularly relates to a self-recovering energy dissipation support with a shape memory alloy damper. The self-recovering energy dissipation support includes a core shape memory alloy damper and cross-shaped steel columns, wherein the shape memory alloy damper includes two sets of inner and outer sleeves. A sliding groove is arranged between the inner sleeve and the outer sleeve, so that the inner sleeve and the outer sleeve can slide relative to each other along a track. The two sets of inner sleeves are connected through pre-stretched shape memory alloy ribs I. The inner sleeves and the outer sleeves are connected through pre-stretched shape memory alloy ribs II. An outer end plate of the shape memory alloy damper is connected with the cross-shaped steel columns.

This invention relates to architecture techniques, and more particularly to an assembled double steel-concrete composite shear wall embedded with a damping interlayer, which includes a double steel layer, a double damping interlayer and a concrete layer. The shear wall is formed by bolted bar joints. The double steel layer includes two first steel plates which are arranged along a length of the assembled double steel-concrete composite shear wall in a parallel manner and two second steel plates along a width of the assembled double steel-concrete composite shear wall. The double damping interlayer includes a first damping interlayer which locates between the first steel plates and the concrete layer and a second damping interlayer which surrounds the bolted bar joints and is surrounded by a steel tube.

A high-precision fiber Bragg grating dislocation sensor, including a fiber Bragg grating, a loose tube, a tension spring, a sliding rod, a positioning piece, a sheath, a stainless steel tube, a transmission rod and a fastener. The sliding rod, the tension spring, the positioning piece, the fiber Bragg grating and the sheath are connected in series, and are provided in the precision stainless steel tube successively. The mechanism of the dislocation sensor is that an elastic force, converted from the local uneven settlement of the settlement joint, is applied on the bare fiber Bragg grating, so that the bare fiber Bragg grating suffers an axial stress and a strain is generated by itself, and the central wavelength of the fiber Bragg grating is further changed, allowing for the monitoring of settlement.
