A robust interaction prevails between the in-plane and out-of-plane seismic performance of infill walls, where in-plane damage often diminishes the out-of-plane bearing capacity of infill walls. A finite element model for RC frames with infill walls was established and validated against experimental data, and extensively employed in numerical analysis. The objective was to delve into the seismic performance of masonry infill walls under bidirectional loading, considering the effects of loading modes, aspect ratio, slenderness ratio, and block compressive strength on the out-of-plane bearing capacity of infill walls with prior in-plane damage. Based on experimental data and parameter analysis, a formula for predicting out-of-plane bearing capacity reduction factors of masonry infill walls with prior in-plane damage was proposed. A new comprehensive geometric parameter was introduced considering the mechanism of out-of-plane load transfer for infill walls. The new formula exhibited a superior fit with experimental data compared to existing equations.","PeriodicalId":516737,"journal":{"name":"Industrial Construction","volume":"267 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140468027","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}

Weng, Fei GAO","doi":"10.3724/j.gyjzg23081112","DOIUrl":"https://doi.org/10.3724/j.gyjzg23081112","url":null,"abstract":": To address the insufficient research on the measurement of static and dynamic deformations of super high-rise buildings during the construction stage, a structural health monitoring (SHM) system was installed on the main structure of a practical super high-rise building with a height of 335 m. Thus the temperature deformation, vertical deformation, and dynamic displacement of the main structure during the construction stage were measured and analyzed. The uneven distribution of temperature in the main structure during the construction stage was identified, and the strain characteristics of the structure under the influence of temperature were analyzed. The results showed that the strain caused by seasonal temperature difference was greater than the strain caused by the self-weight of the upper structure and the concrete shrinkage and creep over the same period. The developments of the vertical deformation and the inter-story uneven deformation during the construction stage were explained. The degree of uneven deformation increased with structural height and time. The maximum deformation difference among the points of the same floor was 5.3 mm. The axial stress of the girder was positive correlated with the difference in vertical strain between the two ends of the girder. The difference in vertical deformation between the outer frame and the core tube could lead to tensile cracking in the girder. A structural dynamic displacement estimation method based on Kalman filtering was proposed, which could improve could the accuracy of dynamic displacement estimation by fusing acceleration data and strain data, and could accurately estimate the dynamic displacement of super high-rise building under dynamic construction loads.","PeriodicalId":516737,"journal":{"name":"Industrial Construction","volume":"46 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139640845","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}
