Ruukki’s Friends Arena

(Issue of a magazine 4/2015, page 114)

A press tour held by Ruukki for a number of leading Russian media including Tall Buildings magazine took place from October 20 to 22. The tour focused on important and topical issues, namely the ways to increase the soperational lifetime of buildings being currently under construction. During the press tour, its participants visited the capitals of Finland and Sweden – Helsinki and Stockholm where they got the chance to meet Ruukki representatives and explore the construction process.

Optimization of the Structural Systems of the Inchon Tower

(Issue of a magazine 3/2015, page 90)

The proposed 151 story Multiuse Inchon Tower is located in the Songdo Inchon Free Economic Zone and founded on new reclaimed land. The 600m tall tower is composed of approximately Thirty (30) stories of office floors, seventeen (17) stories of hotel & other supporting facilities, 100 stories of residential floors, and several levels of mechanical plant floors. The base of the tower consists of retail, future subway station, and several levels of parking below grade.

Design-Basis Substantiation of Load Bearing Capacity of the Evolution Tower

(Issue of a magazine 3/2015, page 98)

In the previous issue of Tall Buildings magazine the readers had the opportunity to learn the complicated multi-phase story of creation of the Evolution Tower in the MIBC Moscow- City. The offered article represents to the readers a look from a slightly different perception. The “foundation” of any architectural masterpiece is in the accurate calculations. Slightly paraphrasing our classic poet, one may say that it is nowhere else but in architecture the harmony is proved by Maths.

Interactive Aerodynamic Design of Supertall Buildings

(Issue of a magazine 3/2015, page 104)

As modern tall and supertall buildings (often of non-orthodox architectural forms) are becoming taller and more slender they also become more sensitive to dynamic windinduced excitation, especially in the cross-wind direction which is often driven by vortex-shedding excitation. The importance of such crosswind excitation and its intimate relation to the architectural form of a tall building is well known [Shimada et al. (1989), Hayashida and Iwasa (1990), Dutton and Isyumov (1990), Miyashita et al. (1993), Kareem et al. (1999), Tamura et al. (2011)] and has now also been considered in the current draft of the new Chinese Building Code (GB 50009-201×). It is however difficult to intuitively predict the impact of building form on vortexshedding, and so lateral wind loading and wind-induced accelerations, which are often critical factors for the structural efficiency of a tower, cannot always be appropriately considered and addressed.

Design of Sustainable Asian Supertall Buildings for Wind

(Issue of a magazine 3/2015, page 112)

The sustainability of supertall buildings is a laudable goal and general enough in its statement to allow interpretation within all areas of tall building design. From a wind engineering viewpoint, the design of sustainable super tall buildings translates in one sense to efficiency and in another to long-term performance or durability. Design efficiencies related to good consideration of wind – form, structure, material – result in lower initial costs and carbon footprint.

TP-50300. Eleborated Solutions - Great Opportunities

(Issue of a magazine 2/2015, page 86)

Perhaps, no modern building design would be complete without translucent aluminum structures. There will not be enough time to enumerate all the good qualities of this material. Well, it is not even worth doing so because an aluminum is probably the most widely used building material in the world.

Deep Foundations

(Issue of a magazine 2/2015, page 90)

Currently designers and constructors often face the challenges of implementing projects of high-rise buildings and unique structures due to the fact that the foundation has relatively deformed grounds whereas the load on the foundation is often enormous and it can reach 1000 kPa. At the same time the high-rise structure engages a huge amount of ground directly under the foundation as well as behind the excavation wall of the building under construction.

Different Approach to the Aerodynamic Performance of Tall Buildings

(Issue of a magazine 2/2015, page 96)

This paper examines the use of Fluid-based Aerodynamic Modification (FAM) methods derived from flow control techniques first developed for the aerospace industry. Instead of relying on the adjustment of the solid material within the structure to improve the aerodynamics of a tall building, fluid based active flow control is added to the building systems’ matrix to manipulate the building boundary layer and achieve a desired performance for both the interior and exterior. Experimental results are presented to demonstrate proof of concept for the FAM approach to tall building aerodynamic modification.

Tall Building Models with Various Unconventional Configurations. Aerodynamic Characteristics

(Issue of a magazine 2/2015, page 104)

Tall buildings have been traditionally designed to be symmetric rectangular, triangular or circular in plan, to avoid excessive seismic-induced torsional vibrations due to eccentricity. However, recent tall building design has been released from the spell of compulsory symmetric shape design, and free-style design is increasing. This is mainly due to architects’ and structural designers’ challenging demands for novel and unconventional expressions.

Calculations of Wind Loads on Tall Buildings

(Issue of a magazine 2/2015, page 110)

The example of how the method of numerical simulation of the three-dimensional aerodynamics is used to define wind loads on the bearing and facade elements of a residential complex. In Russia design, construction and operation of high-rise buildings of very bold architectural forms and authentic design solutions and their space-saving projects (Moscow International Business Center “Moscow City”, “Aquamarine” in Vladivostok and many others) are constrained by the fact that the current construction rules and regulations (CR&R) do not provide guidelines to define shape factors for original in form and large-scale structures, most tall buildings among them.
