The invention discloses a bamboo-shaped round rod energy consumption rod comprising a core part, an outer restraint part and a locating pin. The core part is composed by connecting a plurality of energy dissipation sections, intermediate limiting sections, bamboo sections and two-end connecting sections along the longitudinal coaxial axis. The intermediate limiting sections are located in the middle of the core part. The bamboo sections and the energy dissipation sections are distributed at intervals, arranged on the two sides of the intermediate limiting sections and form a whole together with the intermediate limiting sections, and the two ends of the outer sides of the bamboo sections and the energy dissipation sections are fixedly connected with the two-end connecting sections to form the core part. The cross sections of the intermediate limiting sections, the bamboo sections and the two-end connecting sections are all circular. First holes are formed in the middles of the intermediate limiting sections in the diameter direction. The energy dissipation sections are manufactured by cutting of round rods in the length direction, so that the cross sections of the energy dissipation sections are two parallel opposite sides, the other two short sides are original arc lines, under the effect of the axial tensile pressure, the energy dissipation sections of the core part enter yielding through the formed new cross section areas, while the intermediate limiting sections, the bamboo sections and the two-end connecting sections always remain elastic.

The invention belongs to the field of fixed buildings, and relates to a gradient mechanism shear wall structure and a construction method thereof. In this gradient mechanism shear wall structure, a low-strength concrete area and a rocking support are set between the reinforced concrete shear wall and the foundation. The upper support and the lower support are composed of protruding teeth on the lower end of the upper support, and grooves on the upper end of the lower support. The grooves and the protruding teeth cooperate with each other to ensure that the upper support can rotate around the side edge of the lower support. At the same time, the rocking support has the ability to resist compression and shear. The low-strength concrete area and the swing support in the wall of the present invention can make it have the dual functions of the traditional shear wall and the swing wall, and the transformation of the wall function mechanism is realized through the gradual withdrawal of the low-strength concrete area. The invention can effectively avoid the brittle shear failure and instability failure that are prone to occur in the traditional shear wall structure under the action of earthquake, and make the damage mechanism of the structure more clear and controllable.

The invention discloses a construction method of a soil covering corrugated steel plate bridge. The constructed soil covering corrugated steel plate bridge comprises a main arch and a soil filling layer covering an outer side of the main arch, wherein the main arch comprises load-bearing arch rings and prestress reinforcing structures arranged on an outer side of the load-bearing arch rings. Whenthe soil covering corrugated steel plate bridge is constructed, the method comprises steps that 1, the bearing arch rings are spliced; and 2, soil filling layer construction is performed. The method is simple in step, reasonable in design, easy and convenient to construct and good in using effect; a prestress reinforcing structure is adopted for carrying out sectional type overall reinforcing of the spliced type bearing arch rings, the structure and the arrangement position of each prestressed rib group in the prestressed reinforcement structure are limited, so integrity and stress performanceof the constructed and formed arch rings can be effectively improved, durability of the arch rings can be effectively prolonged, and integrity and overall rigidity of the constructed and formed soilcovering corrugated steel plate bridge are ensured.

The invention provides an unequal-strength wall beam joint based on steel plate hoop confined concrete laminated short columns. The unequal-strength wall beam joint comprises wall vertical steel bars, wall stirrups, first strength grade concrete, second strength grade concrete, steel plate hoops and short vertical bars. The joint core area is poured with first-strength-grade concrete which is the same as a beam plate, a steel plate hoop confined concrete laminated short column is arranged in the joint core area, and the steel plate hoop confined concrete laminated short column is provided with a steel plate rib and a short vertical rib. The unequal-strength wall beam joint based on the steel plate hoop confined concrete composite short column is high in construction efficiency, small in construction difficulty and good in anti-seismic property.
