In order to quantify the characteristics of the entire instability evolution process of concrete, the temporal and spatial evolution characteristics of acoustic emission in the whole loading process of concrete specimens drilled in situ from bridge pile foundation structures were studied and synchronous monitoring tests of axial compression and acoustic emission were conducted. The relation between the whole process of compressive instability and the acoustic emission ringing counts, energy release, focal locations and other characterization parameters were analyzed. Then, a quantitative description of the correlation between the loading process and acoustic emission characteristics was obtained, and its instability evolution process was analyzed. The results indicated that the stress of concrete specimens under axial compression was consistent with the change law of the acoustic emission ringing counts and energy release with times, and the acoustic emission positioning points mainly located in a macro “positio-ning zone” in the shear stress concentration area, which was consistent with the development and failure of concrete cracks. The loading stage of concrete could be quantitatively judged according to activity of acoustic emission, which could reflected the critical characteristics of concrete instability, and was of great significance to service monitoring of pile foundation concrete.","PeriodicalId":516737,"journal":{"name":"Industrial Construction","volume":"80 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140466338","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}

To clearly understand the profile characteristics of typhoons, many measured profile data of several typhoons were used for the analysis. The measured data were categorized by three factors, namely, the underlying surface categories, the typhoon structural partitions,and the wind speed, and the wind profile data of each category were comparatively analyzed, and the study showed that: the low-level jet phenomena in typhoon wind profiles was related to the underlying surface categories, the typhoon structural partitions, and the wind speed, the low-level jets were more likely to occur at exposure category A, B, larger wind speed, and in the back eyewall region in typhoon; there was a certain relationship between the gradient wind height of the typhoon wind profile and the type of underlying surface and average wind speed. The gradient wind height of exposure category A and B showed an increasing trend from the center of the typhoon outward, while the gradient wind height underground of exposure category C showed a decreasing and then increasing trend from the center of the typhoon outward.","PeriodicalId":516737,"journal":{"name":"Industrial Construction","volume":"23 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140464028","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}

A refined finite element model was established according to the real situation of the rods arrangement of the high-formwork support structure, and the buckling analysis was carried out under a variety of working conditions, so as to obtain the vertical displacement of the key joints during the buckling damage of the high-formwork support structure, and to obtain the alarm threshold value of the intelligent real-time monitoring of the construction. The intelligent real-time monitoring algorithm based on computer vision was developed to monitor the displacement changes of the high-formwork support structure in the construction process in real time, and the algorithm will automatically alarm and guide the elimination of dangers and the protection of construction safety when unsafe displacement occurs. After the construction, according to the theoretical calculation re-sults and the actual measurement results, the finite element model was corrected parametrically, and the corrected finite element model was subjected to buckling damage analysis, and the sizes of the corrected buck-ling vertical displacement and the alarm threshold were compared to illustrate the reasonableness of the alarm threshold. The successful completion of a high-formwork support structure project for a multi-use building verified the effectiveness of the new construction monitoring method proposed in the paper.","PeriodicalId":516737,"journal":{"name":"Industrial Construction","volume":"209 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140462870","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}
