The calibration of hysteretic model parameters is crucial for achieving accurate analysis results in structural seismic assessment. The calibration process is commonly conducted by tuning hysteretic model parameters to align with the experimental results of a single component tested under standardized reverse-cyclic loading protocols. The underlying assumption of such a calibration method is that a structural model at the system level, using a well-tuned hysteretic model capable of accurately replicating the test results of a single component under a standardized incremental cyclic loading protocol, can predict the dynamic response of the structural system subjected to ground motion excitations with an acceptable level of accuracy. However, due to the simplified and often unrealistic loading protocols used for model calibrations, this assumption has been challenged recently by both numerical and experimental studies. In this paper, calibration methods utilizing more realistic loading histories are evaluated and compared to more conventional incremental cyclic loading-based protocols. The evaluation of calibration methods is carried out by quantifying the calibration relevance, utilizing a framework of virtual experiments that incorporates uncertainties in hysteretic model parameters. Analyses are conducted based on a case study of BRB components and BRBFs. Additionally, four calibration error quantification methods, considering characteristics in the transitional and plastic ranges of hysteresis curves of BRB, are proposed and compared. The results demonstrate that it is in fact advantageous to use realistic loading histories in component calibration of BRBs. An improved formulation of the calibration error is also proposed for the optimization of hysteretic parameters.</div></div>","PeriodicalId":11763,"journal":{"name":"Engineering Structures","volume":"325 ","pages":"Article 119406"},"PeriodicalIF":5.6,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, this paper summarizes, compares, and evaluates three kinds of collapse failure criteria in literature for reinforced concrete (RC) multi-story frames subjected to column removal scenarios, including the displacement-based criterion, the resistance-based criterion, and the energy-based criterion. Totally, 48 deterministic cases and 480 stochastic cases for six different planar RC frames subjected to 48 different column removal scenarios are studied in the progressive collapse analyses to evaluate the effectiveness and performance of the three kinds of criteria. In the stochastic analyses, the depth of the concrete cover and the key material mechanical properties for both concrete and reinforcing steel are chosen as random inputs, where the uncertainties are observed to have great influence on the collapse limit states. The results demonstrate that the different structural designs and the uncertainties in structural parameters will lead to different collapse limit states, which are strongly linked with the specific failure modes or paths during the progressive collapse. The code-compliant seismic design can significantly improve the deformation capacity of the RC frames and allow sufficient development of load redistributions. In such cases, the empirical collapse failure criteria including both the deformation-based and the resistance-based criteria adopting an empirically prescribe deterministic threshold may fail to accurately determine the collapse limit states. None of them can be adaptive to different structures with different failure modes or paths, either too conservative or too much overestimating the performance. Conversely, the energy-based criterion adopting a physical approach rather than an empirical constant threshold is a physically-based and problem adaptive approach, which can be adaptive to different structures with different failure modes or paths according to the specific computational results. Hence, the energy-based criterion shows the best performance for determining the collapse limit states and is less affected by the different failure modes or paths.</div></div>","PeriodicalId":11763,"journal":{"name":"Engineering Structures","volume":"325 ","pages":"Article 119379"},"PeriodicalIF":5.6,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142757318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multi-keyed dry joints are currently the most commonly used solution in these discontinuity zones. Employing high-strength concrete is becoming increasingly common in civil engineering given its higher strength and improved durability. It specifically allows higher prestressing levels in PCSBs. Using self-compacting concrete enhances workability and adding steel fibres improves mechanical properties. The existing scientific literature includes experimental tests to analyse the shear behaviour of castellated dry joints in different concrete types. However, no experimental tests appear specifically for the castellated dry joints made with high-strength self-compacting concrete (HS-SCC) with and without steel fibres. Therefore, this experimental study conducted 31 push-off-type tests to analyse the behaviour and shear capacity of dry joints made of HS-SCC by investigating the influence of adding steel fibres to the concrete mix. The study examined crack patterns, load-displacement behaviour, failure modes and different (cracking, ultimate and residual) loads. The addition of steel fibres improved joints’ shear capacity. However, brittle behaviour was observed after reaching ultimate load when using HS-SCC, even when steel fibres were added to the concrete mix. Finally, the adequacy of existing formulations was analysed.

To address this gap, this paper presents an experimental investigation for strengthening of shear-critical deep beams using high-strength fiber reinforced concrete (HFRC) jackets. The experimental program involves testing three large-scale deep beams, including a reference specimen and two strengthened beams with thin HFRC jackets of different thicknesses (34 mm and 26 mm). The HFRC jackets featured straight steel fibers with a volumetric ratio of 1.13 %. According to the experimental results and analysis, it is found that an HFRC jacket of 34 mm thickness upgraded the strength by around 25 % and enhanced the crack control by reducing crack widths by around 50 % at the same absolute load with respect to the reference specimen. From the measured deformed shapes of the compression zone of the specimens, it is concluded that the main principles of the two-parameter kinematic theory of deep beams remain valid for HFRC-strengthened members, and these principles can be used to establish a complete modelling approach for such members.</div></div>","PeriodicalId":11763,"journal":{"name":"Engineering Structures","volume":"325 ","pages":"Article 119404"},"PeriodicalIF":5.6,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142744968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The BO technique involves the creation of a web opening at the beam end near the joint to weaken its flexural capacity. In order to offset the reduced shear capacity due to the web opening, a fiber-reinforced polymer (FRP) shear strengthening system also needs to be applied around the opening. However, all previous relevant studies have been focused on the behavior of RC beams with FRP-strengthened web openings. To further verify the effectiveness of this technique, this study conducted experimental and numerical evaluations of RC joints with beam web openings under cyclic loading. Three full-scale RC interior beam-to-column joints were fabricated and tested under lateral cyclic loading and the results were evaluated in terms of failure modes, hysteresis behavior, ductility, energy dissipation, and stiffness degradation.

The test results showed significant improvements in the load-bearing capacity, ductility, and stiffness of the CFST columns after strengthening by high-strength steel tubes. For strengthened columns, there was a general upward trend in the improvement of load-bearing capacity when Q460, Q550 and Q690 steel tubes were used for strengthening relative to the use of Q235 steel tubes. However, the specimens strengthened with Q690 steel tubes showed corner cracking during loading resulting in a lower increase in load-bearing capacity of some of their specimens than the specimens strengthened with Q550 steel tubes. Therefore, it is recommended to use high-strength steel tubes with strength grades of Q550 or lower for reinforcement projects.
