Analysis and Reflection on the Green, Low-Carbon, and Energy-Saving Design of the Super High-Rise Building

“…(2) Take point WP2 as the center and draw a 46.6° arc with a radius of 88,380 mm, and then take WP1 as the center and rotate the circular section 120° clockwise and counterclockwise to form three arcs; (3) Take the point WP3 as the center, and take R2 as the radius of the arc segment to determine the three small arcs and connect them to the large arc to form a triangular plane; (4) Take one-third of the radius from the midpoint of the arc, and make an angle of 95° symmetrically around the radius from the obtained point. Cut the small arc with the two sides of the angle to form a "V" mouth; (5) The complete reference plane profile is determined as shown in Figure 3. As is shown in Figure 3, the overall geometrical form of the Tower Building in Shanghai Tower can be simply described via the following four control points (Figure 4):…”

“…Given the height and scale of high-rise structures, they are particularly susceptible to wind forces, making wind load a critical factor that must be carefully addressed. Thoroughly considering wind loads can enhance a building's resilience and safety, ensuring stable operation during extreme weather conditions, reducing disaster risks, and safeguarding urban residents [5,6]. Additionally, scientifically designing building facades and ventilation systems contributes to optimizing energy usage, improving building efficiency, and promoting environmental sustainability in cities.…”

Research Progress on Shear Characteristics and Rapid Post-Disaster Construction of Narrow-Width Steel Box–UHPC Composite Beams

“…With the continuous development of bridge construction, the number of bridges in mountainous areas is increasing day by day [1], and the rapid development of bridges after a disaster has become an important research topic. Taking the mountainous area of Sichuan, China as an example, the region is prone to frequent geological disasters, such as debris flow and earthquakes [2]. The necessity of the rapid reconstruction of bridges after a disaster is reflected in the following aspects: providing temporary shelter and infrastructure, restoring social order and economic activities, reducing the long-term impact of disasters, and improving the efficiency of emergency rescue are important links in post-disaster reconstruction.…”

“…The steel beams utilize a separate body combination method, resulting in lightweight unit components that facilitate factory prefabrication and transportation in mountainous regions. (2) The bridge can be rapidly erected and constructed without the need for large lifting equipment. During construction, workers do not have to work in the steep gullies and riverbeds that are common in mountainous regions, leading to significant savings in support materials and labor [30].…”

Factors Affecting the Willingness of Arab Residents in Israel to Pay for Green Buildings: Results of a Survey among Potential Homebuyers in Acre and Nazareth

“…Green buildings (GBs) create and use efficient and pro-environmental models for the design, construction, operation, maintenance, and renovation of buildings [1,2]. In addition to their environmental advantages, GBs can increase safety, durability, and resilience under extreme environmental conditions, such as progressive collapse and seismic activity [3,4]. The growing awareness to these benefits has led to the emergence of different GB rating systems around the globe, such as LEED (Leadership in Energy and Environmental Design) in the USA [5] and BREEAM (Building Research Establishment Environmental Assessment Method) in the United Kingdom and the European Union [6].…”
