Effect of Ground Stack for Additional Internal Force and Deformation of Underground Pipeline

Hongyuan Xiong — Mon, 25 Nov 2024 16:19:33 +0800

Based on a three-dimensional finite element model of an underground pipeline, the influence of additional ground loads on the stress characteristics of the pipeline was studied. Furthermore, the effects of different soil properties, load locations, and varying burial depths on the pipeline’s stress characteristics were analyzed. The research results show that as the distance between the load center and the pipeline axis increases, the positions of the pipe’s maximum displacement, bending moment, and shear force along the axis decrease significantly. However, when this distance reaches a certain value, the pipeline’s maximum vertical displacement and internal forces approach zero. Different pipelines exhibit minimum values of maximum axial displacement and vertical displacement in soft soil, while maximum axial displacement occurs in clay, and the largest vertical displacement is observed in sandy soil. The maximum axial displacement of UPVC pipes in clay is twice that of soft soil. The vertical displacement of pipes made from different materials increases with burial depth, but for concrete and steel pipes, the maximum axial tension increases significantly with depth, whereas the change in UPVC pipes is more gradual.

Jiayi Su — Thu, 28 Nov 2024 11:33:42 +0800

To cope with climate change, the Chinese government took the lead in advocating the aim of a Carbon peak by 2030 and carbon neutrality by 2060. In China, the total carbon emission of the whole construction process in 2020 was about 5.08 billion tons of carbon dioxide (CO₂), accounting for about 50.90% of the national carbon emission. Consequently, researchers come up with a series of standard assessments for green building optimization measures. Through analysis and comparison of Leadership in Energy and Environmental Design (LEED), WELL Building Standard (WELL), Building Research Establishment Environmental Assessment Method (BREEAM), and Evaluation Standard for Green Building (ESGB) standards, this study will draw conclusions on optimizing ESGB in terms of weighting, evaluation rating, and carbon emission calculations.

Yinghui Li, Dongya An — Wed, 27 Nov 2024 16:40:18 +0800

To study the seismic resilience of a concrete-framed hospital building with viscous dampers, the elastoplastic time history analysis of a three-story concrete-framed hospital building under moderate and rare earthquakes was carried out by finite element analysis software. The structure’s overall response was studied, meanwhile, the seismic resilience of the building was evaluated from three aspects: repair cost, repair time, and casualties. The results show that viscous dampers can effectively reduce the repair cost, repair time, and casualties under earthquakes. Compared with the structure without dampers, the repair cost and repair time of the structure with dampers have been reduced by 67% and 69% respectively under moderate earthquakes, 42% and 39% respectively under rare earthquakes, and the seismic resilience grade has been increased from zero to one star.

Evaluation of Thermal Comfort in Urban Parks in Guangzhou City

Zhanqian Wu, Soo-bong Kim , Haoyu Gu — Thu, 28 Nov 2024 09:25:50 +0800

Thermal comfort evaluations for Yuexiu Park, Lushan Park, and Baiyun Lake Park in Guangzhou were conducted using field meteorological data collection, visitor questionnaires, and literature reviews. It analyzed the impact of green coverage, water body layout, and facility configuration on thermal comfort. The results showed that good green and water body design effectively lowered the temperature in the park and improved the thermal comfort of visitors, but the insufficient facility configuration in some open areas affected the experience. The visitor’s experience is closely related to the natural environment and facility layout of the park. Therefore, in the future, park design should pay more attention to the rational configuration of shading, ventilation, and cooling facilities to improve thermal comfort, and encourage citizens to participate in the construction and management of parks to improve ecological quality and user experience. This study provides a reference for the improvement of thermal comfort in urban parks in Guangzhou and aims to promote the sustainable and human-oriented development of urban park design.
