Abstract ：
An innovative square steel tube confined rubberized concrete column is proposed in this study to alleviate the pollution from waste rubber and improve the mechanical properties of conventional concrete. The axial compressive behavior of square steel tube confined rubberized concrete (RuSTCC) stub column is experimentally studied. A total of thirty-two specimens, including four square steel tube confined concrete (STCC) stub columns and twenty-eight Ru-STCC stub columns, were fabricated and tested. The variables included rubber particle volume replacement ratio, steel tube thickness, rubber particle size and concrete strength grade. The failure mode, axial ultimate compressive strength, rigidity, ductility, strain characteristics, and confinement effects were analyzed. The results show that the failure modes of Ru-STCC specimens were the core concrete shear failure and steel tube buckling. Ultimate axial compressive strength and rigidity were found inversely proportional to the volume replacement ratio, When the volume replacement ratio reached 20%, the ultimate axial compressive strength and rigidity reduced by more than 20%. With the increase of steel tube thickness, the ultimate axial compressive strength increased by more than 10%. Concrete strength grade and rubber particle size have significant effects on rigidity and ductility, respectively. In addition, the differences between square concrete-filled in steel tube (CFST), rubberized concrete-filled in steel tube (Ru-CFST), STCC, and Ru-STCC stub columns were discussed by compressive strength and deformation capacity. The axial ultimate compressive strength of square Ru-STCC specimens was evaluated using various calculation models. The simplified formulae for the prediction of axial ultimate compressive strength were also presented.

Abstract ：
To meet the requirements of practical engineering, mega steel-reinforced concrete (SRC) columns have been used in super high-rise buildings in recent years. Previous studies on SRC columns primarily focused on simple H-shaped and cruciform steel sections; insufficient attention was paid to mega columns, which are frequently designed with complex steel sections and high-strength concrete. In this study, four 1/6 scaled mega steel-reinforced high-strength concrete (SRHC) rectangular columns with cross-sectional dimensions of 700 mm x 565 mm and various steel ratios and concrete strengths were tested under one-way repeated compression to examine the damage evolution, load-axial deformation response, axial bearing capacity, ductility, stiffness degradation, strain development, restoration, and energy dissipation capacity. The test results indicated that increasing the steel ratio effectively alleviated crack widening and concrete spalling and advanced the bearing capacity, ductility, stiffness, restoration, and energy dissipation capacity. With an increase in concrete strength, the peak load, stiffness, restoration capacity in the elastic-plastic stage, and the energy dissipation capacity in the elastic stage improved, whereas the ductility was sharply impaired, resulting in more abrupt damage. Three provisions were examined to calculate the bearing capacity with conservative estimation. Hence, a theoretical model considering the confinement from the stirrups and steel sections was presented to predict the axial strength with a desirable accuracy. Furthermore, a finite element model was developed to perform the damage evolution and parametric study.

Abstract ：
Circular concrete-filled steel tube (CFST) columns, which are widely used in high-rise and super high-rise buildings, have good mechanical performance. Low-cyclic loading tests were conducted on eight large-sized specimens with different shear-to-span ratios to investigate the seismic performance of circular CFST stub columns with different inner constructions (an internal circular steel tube, built-in partitions, vertical stiffeners, circumferential stiffeners, and a built-in reinforcement cage). The results show that built-in partitions coordinated the common deformation of the internal and external steel tubes, providing the specimen with the best seismic performance. By setting an internal circular steel tube in circular CFST stub columns, a significant confining effect on the core concrete was generated and the deformation of the external steel tube was well developed, which significantly improved the seismic performance of the specimens. Setting circumferential stiffeners had a significant confining effect on the radial deformation of the steel tube, and placing vertical stiffeners between the circumferential stiffeners had an obvious effect on preventing local buckling and improving the flexural capacity of the steel tube. The energy dissipation capacity of the specimens with different inner constructions was better when the shear-to-span ratio was smaller. A method for calculating the peak bearing capacity of such circular CFST stub columns is proposed, which can accurately predict the peak bearing capacity of the columns and provide a basis for the calculation of their application in practical engineering.

Abstract ：
A prefabricated structure composed of a lightweight concrete filled steel tube (CFST) frame and an embedded steel plate (ESP) composite wall is proposed, known as a CFST frame-ESP composite wall. To study the seismic performance of the prefabricated structure, low reversed cyclic loading tests of six full-scale specimens were performed, including five CFST frame-ESP composite walls with different wall details and one bare frame. The failure characteristics, hysteretic characteristics, bearing capacity, stiffness degradation, and energy dissipation capacity of the specimens were compared, and a simplified model was used for the ESP composite wall. Based on OpenSees finite element software, finite element simulation and parameter analysis were performed using a simplified model. The calculated results agree well with the experimental results. The results show that the ESP composite wall can improve the bearing capacity, initial stiffness, and energy dissipation capacity of the CFST frame significantly. The use of a rebar brace decreased the concrete damage and increased the ultimate bearing capacity, initial stiffness, and energy dissipation capacity of the ESP composite wall. The mechanical characteristics of the EPS composite wall is considered in the simplified model. The modeling method presented herein can be used to analyze the abovementioned type of structure.

Abstract ：
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.

Abstract ：
To improve the seismic performance of circular concrete-filled steel tube (CFST) columns with large dimensions, circumferential stiffeners, vertical stiffeners, and reinforcement cages were suggested to be set in the columns. Seven circular CFST column specimens with four internal constructions and two shear-span ratios were designed and tested under low-frequency cyclic loading. The failure modes, hysteretic behavior, bearing capacity, ductility, stiffness and strength degradation, energy dissipation capacity, and effect on the seismic performance based on different internal constructions and different shear-span ratios were herein discussed and clarified. The test results illustrated that the internal constructions could effectively postpone the local buckling of steel tube and improve the ultimate strength, ductility, and stiffness of circular CFST columns. A finite element (FE) model was developed to carry out the working mechanism and parametric analysis. Finally, a theoretical model to estimate the ultimate bearing capacity of CFST columns with different internal constructions was established, the results obtained from the model were in good agreement with the test results.
