Recent experimental and theoretical studies on ETS bond interfaces have found that debonding defects may occur, in certain scenarios, in the construction process induced by air voids, poor grouting or partially cured adhesives, which negatively influences the bond behavior. Currently, little is known about the influence of localized debonding defects on the performance of ETS reinforcement bar-to- concrete joints at present. Therefore, this work attempts to propose a new analytical model that allows for studying the influence of localized debonding defects on the bond behavior of the ETS system. A cohesive zone model (CZM) with a trilinear bond-slip law is used to describe the nonlinearity of ETS reinforcement-to-concrete interfaces. Experimental investigations were conducted on both FRP and steel bars bonded in concrete using different adhesive types, defect lengths, and bond lengths. The solution proposed emphasised the key difference between “short” and “long” joints: short joints were characterized by a softening behavior in the load-slip curve regardless of debonding defects, while long joints exhibited two peak loads followed by a snap-back behavior in the presence of localized debonding defects. The results showed that the analytical predictions were in agreement with the test data, both revealing degradations of the load capacity of the joint with the increase of the ratio (<em>η</em>) between the debonded and the bonded area, particularly for short bonded joints. However, less sensitivity to the location of debonding defects was observed with minimal changes in the load degradation of both long and short joints. This paper facilitates a better understanding of the interfacial behavior of ETS reinforcement-to-substrate bonded joints with debonding defects.</div></div>","PeriodicalId":48642,"journal":{"name":"Structures","volume":"75 ","pages":"Article 108615"},"PeriodicalIF":3.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using probabilistic hazard and risk theory, an updated probability and risk model is developed to effectively display the seismic fragility features of regional buildings. However, the conventional definitions of vulnerability level and macroseismic intensity have features of fuzziness and randomness, resulting in relatively low quantitative accuracy of the fragility of structures in large-scale regions. This paper improves upon the traditional quantitative indicators of vulnerability level and develops an innovative scale to assess the four typical structure clusters in large-scale regions. The conventional macroseismic intensity measurements and logarithmic fitting model are updated using earthquake hazards, probability and reliability, the Bayesian model, and risk theory. The ground motion parameters and instrument seismic intensity measurements are auxiliary quantitative indicators. An improved vulnerability model of large-scale zonal structures considering updated intensity measures and an optimized nonlinear regression method is proposed. The correctness of the developed model is verified via actual seismic loss survey data (18,622.6086 ×10<sup>4</sup> m<sup>2</sup>) from 57 powerful earthquakes that occurred in Xinjiang, China, from 1993 to 2023.

Four-point bending tests were conducted on six specimens that were distinguished according to shear connectors: steel-bars truss, inverted U-shaped rebar, stud, and their combination. The test results show that USCCBs with inverted U-shaped rebar and the combined connector of steel-bars truss and inverted U-shaped rebar exhibit typical bending failure mode (ductile failure, <em>μ</em> &gt; 10), while that with studs and the combined connector of steel-bars truss and studs show certain brittle failure mode (<em>μ</em> &lt; 5). Specimen using only steel-bars truss connector has good ductility (<em>μ</em> &gt;10), but shows a marked insufficiency of shear interaction (<em>η</em> &lt; 1) due to the lowest bearing capacity, 510 kN. The adequate transverse reinforcement ratio (0.63 %) of the steel-bars truss and the triangular three-dimensional structure could effectively strengthen the anti-splitting ability of the concrete deck. USCCB with only steel-bars truss connector should be designed as partially composite beams, but some inverted U-shaped rebars can be arranged to enhance the shear resistance of the interface accordingly. Additionally, the failure of the stud connector is not conducive to the ductility of USCCB (<em>μ</em> &lt; 5). For structural safety, it is not recommended to use studs in whole or in part as the shear connectors of USCCB with full shear connection. The design methods according to full-section plasticity theory have a good prediction for the ultimate flexural capacity of USCCB.</div></div>","PeriodicalId":48642,"journal":{"name":"Structures","volume":"75 ","pages":"Article 108666"},"PeriodicalIF":3.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying the dynamic response of reinforced concrete (RC) structural panels with openings offers valuable insights into the effectiveness of design strategies. This paper aims to investigate the behaviour of two-way square RC panels with openings subjected to blast loads. Firstly, numerical simulations were conducted to analyse the blast-resistant response of two-way square RC panels with window openings. The results showed that the maximum displacement and damage of the panels with openings were significantly lower compared to solid panels. This reduction is primarily due to the fact that part of the blast waves passes through the opening, thereby decreasing the blast load on the panel. Furthermore, parametric studies indicated that panels with square opening at center exhibited a lower blast response as compared to openings of other shapes and at other locations. Finally, a predictive model for the normalized maximum displacement of RC panels with openings under blast loading was developed using machine learning techniques, providing a reliable tool for future design applications.</div></div>","PeriodicalId":48642,"journal":{"name":"Structures","volume":"75 ","pages":"Article 108712"},"PeriodicalIF":3.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings indicate that corrosion morphology and concrete heterogeneity significantly impact durability and failure, with increased non-uniform corrosion and heterogeneity leading to greater susceptibility to damage and cracking. While the impact of concrete strength is minor, the risk of cover failure rises as strength decreases. The influence of cover thickness and steel bar diameter on structural durability is small, with no significant effect on cover failure patterns.
