Online Public Feedback on Mid- to High-Rise Biophilic Buildings: A Study of the Asia–Pacific Region over the Past Decade
Over the past decade, biophilic architecture has been widely developed across the Asia–Pacific region. However, there is a notable lack of research based on online public reviews focusing on mid- to high-rise biophilic buildings, especially quantitative studies combining traditional architectural design features. This study aims to fill this gap by analyzing the typical floor plans and online public reviews of nine renowned biophilic buildings in the Asia–Pacific region. Using space syntax and natural language processing tools, the design features of typical floor plans and public feedback will be analyzed separately, and their correlation will be evaluated. Additionally, the content of negative and low-score reviews will be categorized to identify issues in current biophilic building designs. The findings suggest that biophilic design can stimulate widespread public discussion, with large direct blue–green elements receiving overwhelming attention. However, biophilic elements can also lead to negative sentiments due to factors like humidity, high temperatures, mold, and insects. This study provides insights and design recommendations for future biophilic buildings, demonstrating the value of biophilic design in public reviews and emphasizing the need to balance these factors to enhance public satisfaction and acceptance.

Research on the Deformation Control Measures during the Construction Period of Super High-Rise Buildings with an Asymmetric Plan
Based on the Guangzhou Business Center project, a typical super high-rise building with an asymmetric plan, taking the construction speed, closure time of mega braces and belt trusses as influencing factors, a parametric analysis on its lateral and vertical deformations, as well as the maximum stress of key structural members was conducted. The analysis results indicated that the construction speed had a relatively small impact on the deformation and the maximum stress of key members. However, synchronous closure of belt truss compared with the delayed closure would result in smaller horizontal and vertical deformation differences, as well as the stress of belt truss. Meanwhile, the closure timing of the mega braces had little influence on the vertical deformation difference and the stress of belt truss. And the earlier the closure, the smaller the horizontal drift ratio, the greater the maximum stress of the mega braces. Further, deformation control measurements were brought forward. On the one hand, FEM simulation was carried out according to the above construction suggestions. On the other hand, real-time monitoring was also used. Finally, by comparing both results, proposed construction deformation control measures and simulation methods were verified.

The Effect of Lateral Load Type on Shear Lag of Concrete Tubular Structures with Different Plan Geometries
Tubular structures are extensively recognized as a high efficiency and economically reasonable structural system for the design and construction of skyscrapers. The periphery of the building plan in a tubular system consists of closely spaced columns connected by circumferential deep spandrels. When a cantilever tube is subjected to a lateral load, it is expected that the axial stress in each column located in the flange frame of the tube is the same, but because of the flexibility of peripheral beams, the axial stress in the corner columns and middle columns is distributed unequally. This anomaly is called “shear lag”, and it is a leading cause of the reduction in efficiency of the structure. In this paper, the possible relation between shear lag and the type of lateral load subjected to these systems is investigated. The above relation is not yet considered in previous literatures. Three various plan shapes including rectangular, triangular and hexagon were modeled, analyzed, designed and subjected to the earthquake and wind load, separately. Further work is carried out to compare the shear lag factor of these structures with distinct plan shapes against different types of lateral load. It is observed that all types of structures with various plan geometry subjected to the wind load had a greater amount of shear lag factor in comparison with structures subjected to the static and dynamic earthquake loads. In addition, shear lag in structures with the hexagon shaped plan was at the minimum.

WTC Finalists Include Tallest Structures
\"The world's tallest building would soar over the New York skyline under two design proposals selected as finalists in the competition to rebuild the World Trade Center site. Both the plan from Berlin-based architect Daniel Libeskind and one proposed by THINK, an international team of design firms, would build structures rising higher than Malaysia's 1,483-foot Petronas Twin Towers, the world's tallest buildings.\" (Buffalo News) Read about the two final designs for the World Trade Center site. The features of each design are described.
