Pseudo-static tests of reinforced concrete pier columns confined with pre-tensioned superelastic shape memory alloy wires

Hui Qian et al.

Summary: This study proposes and tests a novel self-centring shape memory alloy (SMA) wire-confined reinforced concrete (RC) column to enhance the seismic performance and self-centring capacity. Experimental tests were conducted on one common RC pier specimen and eight SMA-wire-confined RC pier specimens to investigate the effects of axial-compression ratio, SMA pre-strain level, and SMA configuration rate. The research results provide new ideas and experimental basis for the external strength gain and rapid recovery of existing RC piers after an earthquake.

Seismic Retrofitting of Nonseismically Detailed Exterior Reinforced Concrete Beam-Column Joint by Active Confinement Using Shape Memory Alloy Wires

R. Suhail et al.

Summary: Most existing retrofitting techniques for nonseismically detailed beam-column joints in RC frame buildings are either based on passive confinement techniques or involve joint enlargement. This study proposes a new technique utilizing shape memory alloys for active confinement to improve the performance of BCJs. Experimental tests demonstrate that the proposed scheme effectively enhances joint capacity, energy dissipation, and damage reduction, while also being easy to implement.

Assessment of various seismic fragility analysis approaches for structures excited by non-stationary stochastic ground motions

Xu-Yang Cao et al.

Summary: This paper performs a probabilistic assessment of structures under non-stationary stochastic ground motions using different seismic fragility analysis approaches. Four commonly used PSFA approaches are adopted and compared. The paper discusses the demand distributions and fragility curves under different limit states for all approaches. It recommends the non-parametric KDE approach for estimating the univariate distribution and suggests the LSR approach for efficient data processing and general trend assessment, the MLE approach for smaller response thresholds and slighter damage conditions, and the KDE approach for larger response thresholds and severer damage conditions. The paper provides insights into the accuracy and applicability of various PSFA approaches and offers a basis for linking probabilistic hazard and risk analyses for performance assessment in future research.

Superelastic Nickel-Titanium (NiTi)-Based Smart Alloys for Enhancing the Performance of Concrete Structures

Mohammad J. J. Alshannag et al.

Summary: Recent advances in materials science have led to the development of smart materials that can adapt to different loading conditions and changing environments. Superelastic NiTi shape memory alloys (SMAs) have attracted attention for their unique characteristics and increasing applications in the building industry. However, there is a lack of research on their use in prestressing concrete beams, seismic strengthening, and fiber-reinforced concrete, as well as their performance in corrosive environments, elevated temperatures, and fires. Additionally, the high manufacturing cost and limited knowledge transfer hinder the wider use of SMA in concrete structures.

Consistent seismic hazard and fragility analysis considering combined capacity-demand uncertainties via probability density evolution method

Xu-Yang Cao et al.

Summary: A consistent seismic hazard and fragility framework considering the uncertainties of capacity and demand is proposed, integrating the probability density evolution method (PDEM) into performance-based earthquake engineering (PBEE). The study introduces a non-stationary stochastic earthquake model using spectral representation of random functions, reflecting the real characteristics of ground motions. Comparisons with four classic approaches verify the accuracy and efficiency of the proposed framework.

Flexural performance of high-strength lightweight concrete beams made with hybrid fibers

Mohammad Alshannag et al.

Summary: This paper presents the flexural response of lightweight high strength concrete beams reinforced with different combinations of steel fibers, crimped polypropylene fibers, and recycled plastic fibers. The results show that the fiber reinforced beams exhibit significantly increased load carrying capacity, flexural toughness, and ductility compared to beams without fibers. The beams reinforced with 0.5% of 60 mm long steel fibers and 0.25% of crimped polypropylene fibers showed the largest increase in load carrying capacity and flexural toughness. Furthermore, the use of recycled plastic fibers successfully enhanced the flexural performance of the beams without compromising their load carrying capacity.

Shape memory alloy reinforcement for strengthening and self-centering of concrete structures-State of the art

Saim Raza et al.

Summary: The degradation of reinforced concrete structures due to aging and extreme loading can cause performance and safety concerns. Shape memory alloys (SMAs) with superelasticity and shape memory effect offer unique properties for restoring and designing RC structures. They can reduce permanent deformations, enhance strength and stiffness, and enable self-centering behavior. However, there is a lack of comprehensive review and guidance on the applications of SMAs in RC structures.

Dynamic and probabilistic seismic performance assessment of precast prestressed reinforced concrete frames incorporating slab influence through three-dimensional spatial model

Xu-Yang Cao et al.

Summary: This paper assesses the dynamic and probabilistic seismic performance of precast prestressed reinforced concrete frames, taking into account the influence of the slab. Through numerical modeling and parametric study, the importance of considering the slab influence is highlighted. The findings emphasize that neglecting the slab influence may result in underestimating or overestimating the structural capacity.
