Structural Design of China Zun Tower

Structural Design of China Zun Tower

(Issue of a magazine 2/2017, page 110)

The erecting 528-meter China Zun tower, which construction started in 2011, will be the tallest building in Beijing once built. The building design inspired by an ancient Chinese vessel “Zun”. The plan dimensions reduce gradually from bottom to the waist and then escalate bigger as it approaches to the top to form an aesthetically beautiful and unique geometry. To satisfy the structural requirement for seismic and wind resistance. The structure is a dual system composed of the perimeter mega structure which is made of composite mega columns, mega braces and belt trusses, and the reinforced-concrete core with steel plate embedded walls. Advanced parametric design technology is applied to find the most efficient outer perimeter structure system. The seismic design basically follows a mixed empirical and performance-based methodology which was verified by the shaking table test and other specimen lab tests. The tower is now half-way in its construction.

Peculiar Features of High-Rise Buildings Design in the USA

Peculiar Features of High-Rise Buildings Design in the USA

(Issue of a magazine 1/2017, page 110)

The article prepared by INFORCEPROJECT company’s Chief Design Engineer and partner Dmitry Zelenov deals with the design process management and regulations, as well as peculiarities of structural solutions for high-rise buildings and calculations for high-rise structures in the USA. Thanks to the work experience acquired in Chicago, when the author of the article had a period of training in Halvorson and Partners (WSP business branch) as a part of the international cooperation and experience exchange program practiced in the company, he was engaged in the design of some local and global projects. He had an opportunity to study and compare regulations and technologies applied in Russia and the United States of America. The article will be interesting to Russian specialists who work on collaborative projects in high-rise construction. 

Tall and Smart

Tall and Smart

(Issue of a magazine 1/2017, page 118)

The article deals with selecting the best structural and architectural solutions existing in the world high-rise construction practice as exemplified by Lakhta Center - a new high-rise complex being under construction in Saint Petersburg. Performing intricate and unconventional construction operations and creating basic complex elements are considered from the point of cost optimization and construction delivery time with account of advent of new technologies and materials, as well as specifics of Russian Building Code and Regulations (SNiPs). 

Aerodynamics of Tall Building Clusters

Aerodynamics of Tall Building Clusters

(Issue of a magazine 4/2016, page 102)
Abstract. The article deals with wind loads influencing clusters of adjacent tall buildings. The results are based on simulation tests carried out in special wind tunnels. The paper considers the effects of the mean component of the wind load on buildings and the effect of peak wind loads influencing the building envelope’s structural elements.
 

Forecast of Base Settlement Progress Based on In-Situ Data

(Issue of a magazine 4/2016, page 106)

The basic methodology to check the correctness of a geotechnical solution adopted is the monitoring of a geotechnical situation, in particular, geodetic observations of settlement progress in buildings and structures, their analysis and forecasting of further behavior.

Innovations Controlled, or How to Ensure High Quality Designs, Not Relying on SNiPs

Innovations Controlled, or How to Ensure High Quality Designs, Not Relying on SNiPs

(Issue of a magazine 3/2016, page 90)
When a building is designed and constructed according to not current regulations, but on project specific technical specifications, then the control of their implementation quality is complicated ipso facto in proportion to the novelty and complexity of engineering solutions. First of all, this is the case of tall buildings. This article deals with an experience gained while constructing a foundation for the Lakhta Center – the northernmost skyscraper in the world.
 
Computer-Aided Design as a Method of the Load Bearing Capacity Research of the Column Base of High-Rise Buildings

Computer-Aided Design as a Method of the Load Bearing Capacity Research of the Column Base of High-Rise Buildings

(Issue of a magazine 3/2016, page 96)
Compression design of columns in modern tall buildings with braced frame structures usually takes into account accidental eccentricity. Compression load at the column base can reach 10,000-15,000 tons. It is reasonable to make such columns using steel and concrete structures with both stiff and flexible reinforcement to create a composite structure [1, 2].
