Additionally, these structures are widely located in the backyard of homes in case of hurricanes, tornados, and/or earthquakes. This paper presents a chronological literature review of investigations and comparisons on characteristics of different type of saferoom/shelter wall systems. The characteristics, scrutinized in this study for each type of wall, include structural strength, construction cost, time to construct, and sustainability of saferoom/shelter walls. The most significant contributions of these studies are identified and presented. The results showed that soilbag shelter walls can be constructed with relatively low cost, relatively shorter time, and being relatively more sustainable compared to other types of shelter walls considered in this study. Soil-filled earthbag specimens are stronger and stiffer than gravel-filled specimens of identical size and stack geometry. Using locally available materials minimizes the energy needed and pollution produced due to material transportations. Furthermore, recyclable waste bags can be used to produce bags in soilbags. A slanted roof can be used in any type of shelter wall to harvest rainwater for each shelter use. Moreover, the literature review indicated that the shelter walls made of CLT, and lumber panels are generally stronger against wind loads (250-mph) compared to walls made of soilbags (225-mph).","PeriodicalId":43844,"journal":{"name":"Journal of Structural Integrity and Maintenance","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45832233","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 bridge has a valuable cultural heritage as it was built in 1908 to serve the Hejaz Railway Line. This study presents a structural assessment of the bridge including a field inspection, experimental investigation, and numerical structural analysis. The study also investigates the efficacy of utilizing in-situ Non-Destructive Testing (NDT) such as Rebound Hammer (RH) and Ultrasonic Pulse Velocity (UPV) tests in the assessment of stone arch bridges. Detailed experimental and numerical investigations were performed to identify the structural integrity of the bridge by evaluating the acting stresses and displacements under static and dynamic loads. Minor deteriorations were found in the bridge’s body due to human and environmental factors. However, the geometrical properties of the bridge have not been significantly changed. The obtained results of the numerical analysis concluded that the bridge can sustain the current imposed dead and traffic loads, but not serve seismic actions. Compressive strength and modulus of elasticity of stone units obtained by RH and UPV tests are in agreement with the laboratory tests. Accordingly, NDT techniques can provide and verify basic mechanical properties that are needed for numerical analyses.","PeriodicalId":43844,"journal":{"name":"Journal of Structural Integrity and Maintenance","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43496286","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}

With reliable deterioration models, highway agencies can efficiently allocate funding for bridge maintenance and customize maintenance schedules to meet agency budgets. The increased public expectation of acceptable levels of service for bridges coupled with other competing needs makes it crucially important to accurately estimate bridge future conditions so that adequate resources may be allocated for repair and reconstruction purposes. Accurately predicting bridge condition is challenging due to the inherent random nature of factors impacting deterioration, the existence of unobserved variables that are not measured, panel nature of the data and the effects of bridge-specific correlation. Without accounting for these factors, the resulting estimated deterioration models may have biased and inconsistent parameter estimates. This article assembled a comprehensive set of bridge and climate data from the National Bridge Inventory (NBI) and the South Carolina Climatology office. Bridge component deterioration models for bridges on state highways in South Carolina were estimated using an ordered probit model with random effects specification to account for the randomness and panel nature of the bridge data. The study results are useful for various bridge management tasks including maintenance programming, budgeting and bridge asset evaluation.","PeriodicalId":43844,"journal":{"name":"Journal of Structural Integrity and Maintenance","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48067571","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}

Further studies showed that reduced ductility and low shear strength were the main reasons for the failure of structural members (such as columns). Hence, considering the incorporation of shear strength and ductility in structural design became vital to enhance resistance to environmental loads (such as earthquake). Low-strength concrete is generally in practice in the progressing countries like Pakistan. Different approaches and methods have been used to retrofit and repair the ageing structures using different techniques. The present study focuses on the experimental investigation of confining of concrete columns by pre-tensioning carbon fibre-reinforced polymer (CFRP) with expanding grout. A number of concrete cylinder specimens were prepared using selected quantities of expanding grout, which produced various initial pressures. The behaviour of pre-tensioned confined concrete with non-pre-tensioned confined and unconfined concrete was compared. It was also indicated that using CFRP along with expanding grout can enhance the engineering properties (axial stress and elastic modulus) of columns. It was comprehended that an increment in the initial confining pressure resulted in increment in axial stress as well as axial and lateral strains.","PeriodicalId":43844,"journal":{"name":"Journal of Structural Integrity and Maintenance","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2022-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44058159","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}
