However, implementing a non-linear analysis and design method in accordance with the Australian Standard for concrete structures (AS 3600) introduces many difficult technical issues into the design, of which the standard provides little guidance. The aim of this study is to provide a framework and general guidance for designers who wish to perform non-linear displacement-based analysis methods for RC wall buildings. The paper will present how these methods can be used in accordance with the Australian Standard for earthquake actions (AS 1170.4) to assess seismic compliance and then provide recommendations for the requirements stipulated by AS 3600, which includes an experimentally validated tension stiffening model, nonlinear stress-strain material curves, mean material properties and material strain limits. The paper is concluded with a case study example of how a displacement-based seismic assessment can be performed using a typical case study building.","PeriodicalId":45617,"journal":{"name":"Australian Journal of Structural Engineering","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79447910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper provides a summary of the mean values and respective coefficient of variation values for the different grades of concrete and reinforcement that make up the database. Distinctive manufacturing trends and variability between suppliers were observed for reinforcement samples and appropriate recommendations have been proposed. Researchers or designers can adopt these values to undertake probabilistic assessments of RC structures. The paper also provides recommendations for mean material properties for the purpose of undertaking non-linear analysis of RC structures. The database of test results also includes early age strength data for concrete, which have been used to provide recommendations for predicting the early age strength of various standard grades of concrete available in Australia. The paper also presents an assessment of the theoretical characteristic values from the database for the various grades of reinforcement and concrete and how they compare to respective specified code requirements.","PeriodicalId":45617,"journal":{"name":"Australian Journal of Structural Engineering","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79877920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the use of precast concrete slab in steel–concrete composite construction is considered as new, hence many factors that affect its behaviour need to be investigated. It becomes interesting when the application of interlocking tongue and groove joints between precast concrete slabs is introduced. For this purpose, a performance comparison between normal precast slab and interlocking tongue and groove precast slab in composite construction is conducted using finite element analysis. Both are designed to have full composite action using bolted shear connector. In this research, a total of five models including a control model were developed to study the flexural behaviour of designated composite beam. The model has been verified against experimental results, which showed a good agreement . Parametric studies were performed to investigate the effects of bolt size and height on flexural behaviour of the beam. The present study demonstrated that the presence of interlocking joints between slabs with larger diameter bolt can efficiently improve the stiffness of the composite system.","PeriodicalId":45617,"journal":{"name":"Australian Journal of Structural Engineering","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74264649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method uses operational strain time-history responses to detect damage in truss elements, and change in support behaviour. Dynamic strain time-history responses obtained under baseline and unknown-state bridge conditions are used to compute the magnitudes of differences in strain values between two successive time-steps. A new damage-sensitive feature (DSF) is proposed as the change in percentage of the square root of the sum of squared values of these magnitudes. After establishing a threshold DSF based on the baseline bridge, further structural change or damage in the bridge could be detected and located by observing the values of the DSFs. The validity of the method is investigated through finite element analysis of a steel-truss railway bridge. It is demonstrated that the proposed method yields promising results for identifying, locating, and relatively assessing the damage, and could be useful even when different operational conditions (i.e. different train speeds and loads) and measurement noise influence the strain data. Therefore, the proposed method has the potential to assist in developing effective maintenance strategies for railway bridges.","PeriodicalId":45617,"journal":{"name":"Australian Journal of Structural Engineering","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73253702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The incremental demand for aggregates in concrete is affecting the environment due to excessive exploitation of natural rocks. In an effort to conserve the natural resources and minimise the adverse impacts of industrial by-products in the environment, it is essential to explore the suitable alternate materials for construction. Under such circumstances, an attempt was made with coconut shell aggregate (CSA) as a substitute for conventional coarse aggregate (CA) in self-compacting concrete (SCC). In this investigation, binary and ternary blended SCC were developed using the mineral admixtures such as rice husk ash (RHA) and silica fume (SF). Two series of SCC were designed with the total powder content of 450 and 550 kg/m3 , respectively, for investigation. The effects of CSA in SCC on fresh and hardened properties were studied and compared with the results obtained without CSA. The results revealed that use of 75% CSA in SCC reduced the density below the threshold level of structural lightweight concrete (1850 kg/m3) in dry state. The CSA-based lightweight self-compacting concrete (LWSCC) possesses good fluidity, deformability, passing ability and filling ability in its fresh state. The compressive strength and elastic modulus of LWSCC were determined and found that the results are decreased after the substitution of more than 75% of CSA. Further, the paper intended to predict an appropriate correlation between compressive strength and elastic modulus of CSA-based LWSCC.","PeriodicalId":45617,"journal":{"name":"Australian Journal of Structural Engineering","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88343507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
