  • The stringing load was added to tower design that consider the active load in 765kV transmission line construction. The nominal auxiliary members of steell tubular tower arm were altered into stress members by means of three dimensional design analysis method. 765kV transmission line construction also use self-standing tower that does not install temporary wire which support the section tower placed between drum field and engine field when stringing process.

  • This paper introduces three distinctive means for the use of a 189-meter high damped structure ensuring safety against earthquake: 1. Realization of L-shaped elevational structural planning: The bottom and top of the tower have belt trusses and hat trusses respectively to restrain the bending deformation. Furthermore, large-capacity oil dampers (damping force 6,000 kN) are installed in the middle part of the tower to restrain the higher-mode deformation. 2. Realization of L-shaped planar structural planning: We devised a means of matching the centers of gravity and rigidity by adjusting planar rigidity. Moreover, viscous damping devices are located at the edges of the L-shaped plan, where torsional deformation tends to be amplified. We call this the "Damping Tail" system. 3. Composite foundation to equalize deformations under different loading conditions: We studied the vertical and horizontal deformations using sway-rocking and 3D FEM models including the ground, and applied multi-stage diameter-enlarged piles to the tower and a mat foundation to the podium to keep the foundations from torsional deformations and ensure structural safety.

  • The Spiral, a supertall tower at the Hudson Yards Zoning District of NYC is an new iconic commercial office tower. The spiraling terraces throughout the height of the building creates unique outdoor spaces at each level for its occupants while introduces structural challenges unlike common office towers. Innovative structural solutions and an integrated connection design and steel detailing delivery process proved to be a key factor in the success of the project.

  • The skylines of many cities worldwide are still defined by the dominant and ubiquitous office blocks of the twentieth century. While there is consensus stating that future tall building typologies should depart substantially from these past models, the inheritance of large and obsolete tall office building stocks presents a problem of global significance. Too old for present corporate models, but too new for gaining public historical importance, the twentieth-century office tower is a typology under threat of extinction. However, the need for a culturally informed strategy of preservation for that generation of tall buildings is seldom advocated. Drawing evidence from the case of Melbourne, Australia, this article presents a methodological pathway to overcome pitfalls of memory and interpretation, which commonly prevent an unbiased assessment of the value and urban contribution of late-twentieth-century skyscrapers.

  • As buildings nowadays become taller in height and larger in size the safety review of lifting plan takes larger portion in construction project management. However, the cost and safety in lifting plan have a contradictory effect on each other. Therefore, an optimization algorithm needs devising as a solution of the contradictory problem. In many cases at construction sites, selections and stability review of tower cranes are assigned to equipment suppliers or field managers, which cause the problems in safety and cost of the projects. To improve the part of the current situation, a study on the optimization algorithm for designing the foundation of tower cranes is conducted in this study, which can be utilized by equipment suppliers or field managers to check the stability of tower cranes easily and promptly without substantial knowledge.

  • Necessity to install control towers has been studied to acquire overseas energy resources and to secure funds. At present, domestic energy companies do business independently. Institutions which support plant EPC companies as partners of package deal are separated. This causes the low records at package deal for overseas resources acquisition. Except UK and USA, nations which have major companies developed overseas energy resources early by promoting a large national company. Consequently, they currently have good records. This study suggests the necessities to install integrated control tower for overseas energy resources acquisition and securing funds and the following are the ways ; 1) promote a large national company by consolidation of separate energy companies, 2) install plant EPC promotion department which support private plant EPC companies, 3) make a integrated control tower in high level government office to connect between a large national company and plant EPC promotion department.

  • Highrise concrete buildings are very sensitive to cumulative and differential shortening of their vertical element such as wall and columns. Inelastic deformation due to creep and shrinkage consist of various factors and load history af actual building is very complicated. Therefore, for the accurate prediction and compensation of axial shortening, special efforts in design and construction phase are required to ensure long-term serviceability and strength requirement. In this paper, axial shortening estimation and compensation procedure is presented, which utilized experimentally determined concrete properties and preliminary load history and computerized approach, in case of Plaza Rakyat office tower, 79-story reinforced concrete building under construction in Malaysia.

  • It is getting more difficult to construct new transmission lines, due to the increase of people's demand resulting from the change of social environment and people's consciousness. In order to solve these complicated conditions. we developed a computer system to support the route selecting and surveying of a transmission line. This paper introdouces the methodology for route selecting, designing, surveying of a transmission line and tower designing process using a computer system.

  • The Lakhta Center is a Multifunction Complex Development (MFCD) consisting of 1) an 86 story office tower rising 462 m above the ground to provide high-end offices for Gazprom Neft and Gazprom Group affiliates 2) a Multi-Function Building (MFB) that includes, a scientific/educational center, a sport center, a children's technopark, a planetarium, a multi-transformable hall, an exhibition center, shops, restaurants, and other public facilities 3) a Stylobate 4) "The Arch, which forms the main entrance to the tower, restaurants, and cafes 5) underground parking and 6) a wide range of large public plazas. While each of the MFCD buildings is technically challenging in its own right, the focus of the paper is to present the development and integration of the structural and foundation systems of the bowed, tapered, and twisted shape of the tower into the fabric of the tallest Tower in Europe.
