The Tall Buildings Reference Book
Format: PDF / Kindle (mobi) / ePub
As the ever-changing skylines of cities all over the world show, tall buildings are an increasingly important solution to accommodating growth more sustainably in today’s urban areas. Whether it is residential, a workplace or mixed use, the tower is both a statement of intent and the defining image for the new global city.
The Tall Buildings Reference Book addresses all the issues of building tall, from the procurement stage through the design and construction process to new technologies and the building’s contribution to the urban habitat. A case study section highlights the latest, the most innovative, the greenest and the most inspirational tall buildings being constructed today.
A team of over fifty experts in all aspects of building tall have contributed to the making of the Tall Buildings Reference Book, creating an unparalleled source of information and inspiration for architects, engineers and developers.
concrete can be poured into clean and “dry” (less than 50 millimeters of water) shafts, nondestructive integrity testing is not needed. Where piles carry heavy loads or high concrete stresses, testing is more critical. Typically, where the concrete stress level exceeds 0.15 f’c, cross-hole sonic logging (CSL) is the preferred method. For lower stress levels, impulse response spectrum (IRS) methods can suffice. Planned coring of representative piles should be done to check concrete quality and
oblique views around and through the urban forest of Midtown skyscrapers. The crystalline form— inspired by the legacy of the 1853 Crystal Palace which once stood adjacent in Bryant Park, and by a quartz crystal from the client’s collection—suggests an appropriate natural analogue, at once organic and urban in nature. Through the building’s exquisitely clear facade, the natural elements are experienced in an immediate and almost sensory way; from the outside, the facade changes with the sun and
outer periphery. The forces thus generated exert torsion on the entire building structure and therefore demand the addition of members to prevent collapse of the columns. The generated horizontal forces are transferred to the inner truss tube via girders that form a horizontal truss, thereby counteracting the torsion that is exerted on the entire building structure. Vibration-control columns fitted with viscous dampers on the column position are arranged at 26 locations, and thus it has been
irrational exuberance, passing the point at which the value of an architectural statement exceeds its cost or risk – though ‘value’ has a number of interpretations. Whilst innovation can be a driver for the supertall and for the ‘super-iconic’, the Burj Khalifa is testament to the fact that this can be just as much about brain power (of the architect and engineer) as anything else. Expertise can create something truly groundbreaking, yet cost effective; as Kurt Lewin (1952: 346) said, ‘there is
vertical communities through greater social interaction and co-presence. In their current guise, sky courts and sky gardens can be deemed semi-public social spaces with public domain characteristics. They form part of a hierarchical network of open spaces that replenishes and complements existing open space programmes on the ground, embodying the critical qualities that define the civic realm and wider community. They are spatially constrained by the tall buildings that retain them, often
