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.

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

(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].

Regulatory Requirements and Facts. Dynamic Analysis of High-Rise Buildings in Terms of Maximum Operating Basis Earthquake (OBE)

Regulatory Requirements and Facts. Dynamic Analysis of High-Rise Buildings in Terms of Maximum Operating Basis Earthquake (OBE)

(Issue of a magazine 2/2016, page 100)

The article deals with developed technique of numerical simulation of the dynamic response of the “foundation - tall building” physically nonlinear spatial system with a certain combination of loads that include intensive seismic OBE impact that is provided by the earthquake accelerogram. The method that was implemented by the Abaqus verified software, is used for the finite element analysis of the design version of a 400-meter high skyscraper with reinforced concrete structures at a 9,5-scale seismic impact.
