In order to promote the application of aeolian sand in steel-concrete composite structures, the aeolian sand concrete columns with an inner square steel tube is proposed in this paper. This kind of column is composed of aeolian sand concrete, reinforcing steel, and an inner square steel tube. The seismic damage behavior of the column was studied through cyclic loading test and damage analysis on seven specimens with different structural forms. The seismic damage indices of the specimens in this study include the failure mode, bearing capacity, ductility, stiffness, hysteresis behavior, and energy dissipation. Then, a damage model of this kind of column is proposed. The study results show that installing an inner square steel tube can significantly improve the seismic damage behavior of aeolian sand concrete columns. This mode of construction can be used to enhance the replacement percentage of aeolian sand. In addition, the damage model proposed in this paper agrees well with the experimental results and can be used to evaluate the damage degree of the aeolian sand concrete columns with an inner square steel tube.

“…Section A-A' where E sum is cumulate dissipated energy; m 1 is the number of the 372 drift ratio up to failure; m 2 is the number of cycles for each drift 373 ratio. In order to compare dissipated energy among specimens, nor-374 malized dissipated energy E N was calculated as [61]: The stiffness (K i ) of the column at the ith drift ratio is defined as 389 [61]:…”

“…The ductility of each specimen was obtained from the hysteresis curves, considering the maximum displacement reached. The energy dissipation capacity was obtained by the area of the trapezoids for each load–displacement cycle, as recommended in, which was designed for nonlinear static methodologies. The hysteretic performance of each specimen was evaluated from the energy dissipated.…”

“…The seismic behavior of UHPFRC columns depends on the axial load level, stirrup arrangement and the fibers content. In the references tested a lot of specimens of UHPFRC subjected to axial loads (columns). According to the results UHPFRC columns with multiple stirrups and commonly used structural steel ratios demonstrated excellent seismic behavior.…”

Ultra-high performance fiber reinforced concrete (UHPFRC) is a unique class of fiber-reinforced concrete featuring ultra-high compressive strength and ductile tensile strain hardening behavior, accompanied by multiple narrow cracking. Although many studies have confirmed its superior mechanical and damage tolerance properties under monotonic or blast loading, limited research has been carried out on the cyclic performance of UHPFRC structural members. This paper proposes the use of UHPFRC to improve the cyclic performance of structural elements. An experimental program was carried out on a large number of UHPFRC beam-column joint specimens under a cyclic lateral load. After the cyclic loading test, the following results were obtained: (a) hysterical performance, (b) maximum load, (c) maximum displacement, (d) the maximum energy dissipation (measured by hysteresis cycles), (e) stiffness degradation, (f ) the cracking pattern, and (g) the cracking area. The analysis showed that UHPFRC specimens have at least 157% higher energy dissipation than nonfiber conventional reinforced concrete (RC). The initial stiffness of UHPFRC specimens without fibers (NF) was at least 23% higher than the RC specimen. For UHPFRC with fiber, initial stiffness was at least 45% higher than RC specimen.
