Published: July 2024

AbstractAt present, there are many control measures for the deformation of subway caused by the excavation of foundation pit. It is worthy of attention that pretreatment measures can effectively reduce the influence of deformation on the subway tunnel under different working conditions. Therefore, the finite element model is established by Midas/GTS to explore the reinforcement effect of two measures of pit bottom reinforcement and isolation pile reinforcement. The results show that: in the excavation of foundation pit, the two schemes have different effects on controlling the deformation of tunnel structure, and the inclination of diameter line is generally smaller. The deformation characteristics of each component structure of the diameter line after the pit bottom reinforcement are similar to those of the unreinforced condition, while the displacement changes of each structure after the isolation pile reinforcement become uniform and reasonable. Isolation pile reinforcement is better than pit bottom reinforcement, especially in reducing the vertical displacement of the structure. The reduction degree of the maximum horizontal displacement after the isolation pile reinforcement is about 24%–31%. Therefore, when selecting the pretreatment method, priority is given to the isolation pile reinforcement method.

Published: July 2024

AbstractPerformance tests were conducted on high abrasion resistance concrete with different coarse aggregate contents and sand replacement rates. The influence of aggregate content on the slump, compressive strength, and impact and wear resistance of concrete was analyzed. The results show that when the ratio of slurry to aggregate is 5:5, the slump and abrasion resistance strength of high abrasion resistance concrete decrease with the increase of sand replacement rate, while the compressive strength increases with the increase of sand replacement rate. At a ratio of 5:5–5, the abrasion resistance of hydraulic concrete reaches its optimal performance.

Published: July 2024

AbstractThe design optimization of the jacket substructure could reduce the cost of energy and the correlated carbon cost. The mass of jacket is optimized with respect to maximum stress and displacement responses. Wind and dead loads were applied at the top of the jacket referenced point. Wave load and foundation boundary were applied using Dload and UEL function in the Abaqus subroutine. Six different parameters were evaluated, including the pile height above mudline, the base width, brace thickness and diameter, and the main leg thickness and diameter. The parametrically optimized model has mass minimized by 16%. The maximum stress at the top of the optimal jacket reduced to 274.91 MPa from 288.70 MPa. The maximum displacement at the top increased to 87.37 mm from 83.88 mm, albeit, lower than the code limit of 175 mm. The absolute value of the maximum rotation at the top reduced from 0.309° to 0.304°, which is lower than the code limit of 0.382°. The pile rotation at the mudline increased by 14%, from 0.120° to 0.137°, nonetheless, lower than the DNV code limit of 0.250°. Initial numerical basis has been developed for the parametric design optimization of the jacket substructure. From the parameter studies conducted mathematical models could be developed for efficient numerical optimization.

Published: July 2024

AbstractIn order to explore influencing factors of stability of laterite subgrade slope under the action of dry and wet cycle, the indoor direct shear tests of compacted laterite under different dry and wet cycles were carried out, and the strength parameters were obtained. The stress correction method was introduced to analyze the influence of the number of dry and wet cycles on the strength of laterite and the influence of stress correction on the analysis results. Based on the results of direct shear tests, Geostudio finite element software was used to simulate the stability and influencing factors of laterite soil subgrade slopes of different heights under different dry and wet cycle times. The results show: (1) The shear strength of laterite decreased with the increasing of the number of dry and wet cycle times, and the shear strength index of laterite after stress correction was added compared with the before correction. (2) With the increasing of the times of dry and wet cycles, the slope stability coefficient gradually decreases as an exponential function. The stability coefficient after correction is increased compared with before correction, and it have great significance to improve the reliability of direct shear test data by using stress correction method in landslide treatment and filling engineering. (3) The stability coefficient of the subgrade slope decreases monotonically with the increase of slope height, and the smaller the slope height of the slope, the better the overall structural stability.

AbstractThe use of recycled concrete can reduce the extraction of natural aggregates, achieve the reuse of construction waste, and thus achieve environmental protection and economic cost savings. In terms of mechanical properties, the use of recycled materials has the effect of reducing the strength and durability of concrete. Diamond sand has high hardness and good durability, and the addition of concrete can effectively improve the strength of concrete. However, there is little research on the content of diamond sand added. This study aims to add diamond sand to recycled concrete and test the effect of diamond sand content on the flexural performance of recycled concrete under the same recycled material content by changing the content of diamond sand. The aim is to make a certain contribution to the optimization of prefabricated structures.

Published: July 2024

AbstractThe core area of the urban central rail transit station is the area with the highest concentration of urban population and the most prominent contradiction. Aiming at the problems of fragmentation of above-ground and underground space, low quality of underground space environment, and lack of sense of place, this article puts forward the concept of three-dimensional place making. By introducing the analysis method of spatial narrative, and taking its advantages in shaping the sense of place, integrating the information of place, and constructing the semantics of place, this paper studies the characteristics of the place making of Shenzhen Huaqiangbei Station and Tokyo’s Shibuya Station, explores the spatial narrative logic that can effectively connect the above ground and underground, proposes the design strategy of three-dimensional place making, and explores the possibility of quantitative study of urban three-dimensional space in station area. The study found that the place making of station area should be based on the characteristics of its own space environment. In the area with high three-dimensional degree, complex space environment and large scale of development, it is appropriate to take the walking network as the framework and use deconstructive spatial narrative technique to create places with “multiple themes, multiple scenes and multiple elements” by segmenting and partitioning, so as to realize the organic integration of various spatial elements. This paper, for the first time, applies the spatial narrative theory and method to the study of place making in the core area of rail transit station, and explores a new way for the study of three-dimensional urban design in the urban railway station area.

AbstractWith the popularization and development of prefabricated buildings in rural areas, the application of prefabricated decoration technology in rural residential environment is becoming more and more important, which has also attracted great attention from academia and industry. However, due to many factors, such as low integration, high cost and low market share, the application of this technology in rural residential environment has obvious obstacles. In this paper, based on the modern digital era, firstly, the relevant theories are extensively studied and sorted out, and then the application of BIM + AR intelligent assembly and decoration technology in rural process is studied by means of practical investigation, empirical research and functional analysis. The research shows that the optimization of application mode can better promote the marketization process of assembled decoration technology and help to optimize the construction of rural human settlements. However, to complete the comprehensive optimization of rural human settlements in rural revitalization, further technology market popularization and market adaptation time are required.

Tiebout sorting in online communities
Authors: Lynham John , Neary Philip R. 
Published: July 2024

AbstractThis paper proposes a stylized, dynamic model to address the issue of sorting online. There are two large homogeneous groups of individuals. Everyone must choose between two online platforms, one of which has superior amenities (akin to having superior local public goods). Each individual enjoys interacting online with those from their own group but dislikes being on the same platform as those in the other group. Unlike a Tiebout model of residential sorting, both platforms have unlimited capacity so there are no constraints on cross-platform migration. It is clear how each group would like to sort themselves but, in the presence of the other type, only the two segregated outcomes are guaranteed to be equilibria. Integration on a platform can be supported in equilibrium as long as the platform is sufficiently desirable. If online integration of the two communities is a desired social outcome, then the optimal policy is clear: make the preferred platform even more desirable. Revitalizing the inferior platform will never lead to integration and even increases the likelihood of segregation. Finally, integration is more elastic in response to an increase in platform amenities than to reductions in intolerance.

Published: July 2024

Abstract
Background
Restrictions during the COVID-19 pandemic influenced a shift to same-day discharge in bariatric surgery. Current studies show conflicting findings regarding morbidity and mortality. We aim to compare outcomes for same-day discharge versus admission after bariatric surgery.

Methods
Subjects included patients who underwent primary laparoscopic or robotic-assisted sleeve gastrectomy or Roux-En-Y gastric bypass at an academic center. The inpatient group included patients discharged postoperative day one, and the outpatient group included patients discharged on the day of surgery. Primary outcomes included the number of emergency room visits, reoperations, IV fluid treatments, readmissions, and mortality within 30 days. Secondary outcomes were morbidity, including skin and soft tissue infection, pulmonary embolism, and acute kidney injury.

Results
1225 patients met the inclusion criteria. In the gastric sleeve group, 852 subjects were outpatients and 227 inpatients. In the gastric bypass group, 70 subjects were outpatients, and 40 were inpatients. The mean age was 44.63 (17.38–85.31) years, and the mean preoperative BMI was 46.07 ± 8.14 kg/m2. The subjects in the outpatient group had lower BMI with fewer comorbidities. The groups differed significantly in age, BMI, and presence of several chronic comorbidities. The inpatient and outpatient groups for each surgery type did not differ significantly regarding reoperations, IV fluid treatments, or 30-day mortality. The inpatient sleeve group demonstrated a significantly higher readmission percentage than the outpatient group (4.6% vs 2.1%; p = 0.02882). The inpatient bypass group showed significantly greater ER visits (21.7% vs 10%; p = 0.0108). The incidence of adverse events regarding the secondary outcomes was not statistically different.

Conclusion
Same-day discharge after bariatric surgery is a safe and reasonable option for patients with few comorbidities.
