摘要 :
There is a growing interest in the development of precast structures. In this paper, a semi-precast high-strength recycled aggregate concrete (RAC) column with high-strength reinforcement was studied, which was consisted of cast-in-situ core concrete surrounded by a precast external shell. Six full-scale columns were fabricated and tested under cyclic lateral load, of which two were cast-in-situ columns and four were semi-precast columns. The penetration of shear reinforcement between precast external shell and cast-in-situ core column, core column diameter and axial load were the major design parameters. The test results showed that all specimens exhibited a good deformation capacity with an ultimate drift ratio greater than 3%. The semi-precast columns had comparable seismic performance with the cast-in-situ columns, indicating that the penetrating shear reinforcement and the core column diameter had little effect on the seismic performance. The core column diameter could be selected according to the practical engineering requirements. Increasing the axial load can significantly improve the lateral load-carrying capacity of the specimens, but would result in larger residual drift ratio, which was adverse to the repairability of the specimens. The flexural deformation and the deformation resulting from slippage of longitudinal reinforcement in the concrete foundation accounted for 50%-80% and 10%-20% of the lateral displacement, respectively, which should not be ignored in the deformation calculation; however, the shear deformation can be ignored. The optimized models applicable to calculate the F-Delta curves of semi-precast high-strength RAC columns with high-strength reinforcement were proposed. Parametric analysis based on the optimized models was carried out to develop N-M curves for various precast external shell or core column concrete strength, and core column diameters.

摘要 :
Three 2-story frame-shear wall structures that integrated the advantages of composite structure and highperformance materials were designed and tested under cyclic lateral loading to develop a high-performance structure with satisfactory seismic behavior and reparability. HRB 600 MPa steel bars (i.e., hot rolled ribbed rebar with nominal yield strength of 600 MPa) and 1400 MPa ultra-high strength (UHS) steel bars were used for vertical component reinforcement, and different reinforcement configurations were taken as the design parameters. The results showed that the proposed structure can be repaired at a large drift of 2% and ensure sufficient collapse resistance capacity as well. The structure only reinforced with HRB 600 MPa longitudinal bars in vertical components showed better energy consumption capacity but serious concrete damage. Replacing all HRB 600 MPa longitudinal bars with an equal strength of UHS longitudinal bars have a more pronounced role in avoiding the deformation and damage concentration in the lower floor and controlling the growth rate of residual drift than partially replaced hybrid reinforced structures. The UHS reinforcement concealed bracing can effectively decrease the shear strength degradation, control the damage of shear wall, and improve the reparability of the structure. According to the failure mechanism, an ideal load-deformation response to reflect the damage state was proposed.

摘要 :
To study the influence of masonry infill walls on the hysteretic performance of reinforced concrete frames, a cyclic experiment was conducted for three two-story and two-span reinforced concrete frame structures, including one reinforced concrete frame without infill walls and two frames with infill walls. Whether the infill walls were constructed in the frames and the type of infilled material were the main parameters of the test. The major results reveal that: the infill walls clearly changed the mechanical mechanism of the frame structure at the early stage of loading, magnified the stiffness and horizontal bearing capacity of the frame structure, and enhanced the energy dissipation capacity of the frame structure, but reduced the deformation performance of the frame structure. In the later stage of loading, the infill walls would no longer work as one with the frame gradually with the failure of the infill walls, and the above performance of the structure would approach the empty frame structure. Moreover, the initial stiffness, energy dissipation capacity, and horizontal bearing capacity of the frame with infill walls of clay hollow bricks were the highest among the three specimens. But due to the strong diagonal bracing effect, the damage to the top of the columns and beam-column joints was serious, the yield displacement was reduced significantly, and the shear failure of the top of the columns and the joints occurred prematurely, which showed poor performance of deformation and ductility. However, the frame with infill walls of relatively soft aerated lightweight concrete blocks showed better performance of deformation and ductility.

摘要 :
为了解决方钢管再生混凝土界面黏结性能不足的问题,进行30个设置加劲肋或栓钉的方钢管再生混凝土推出试验.核心区混凝土采用2种水胶比和3种再生粗骨料取代率.通过试件的破坏形态、荷载-位移曲线和钢管应变,分析钢管内不同构造措施和混凝土类型对黏结性能的影响,并对水平加劲肋试件抗剪强度进行计算.结果表明:纵向加劲肋、水平加劲肋均能有效提高方钢管再生混凝土界面黏结强度、残余黏结强度和耗能能力;纵向加劲肋与水平加劲肋的复合构造改善效果最好,复合构造与2种构造简单叠加结果相比,黏结强度提高5.4%;栓钉构造仅增加初期黏结强度,对残余黏结强度影响不大;随着构造措施的加强,相比于高水胶比试件,低水胶比试件的黏结强度提高更多;再生粗骨料全取代的方钢管再生混凝土黏结性能不稳定;采用的水平加劲肋试件抗剪强度计算方法与试验结果相比偏于安全.
