The Trump International Hotel and Tower, also known as Trump Tower Chicago and locally as the Trump Tower, is a skyscraper condo-hotel under construction in downtown Chicago, Illinois in the United States. Architect Adrian Smith, who worked for Skidmore, Owings and Merrill during the building's planning and design stages, designed the building, named after real estate developer Donald Trump. Bovis Lend Lease is building the 92-story structure to a height of 1,362 feet (415 m) including its spire, with its roof topping out at 1,170 feet (360 m). It is adjacent to the main branch of the Chicago River with a view of the entry to Lake Michigan beyond a series of bridges that cross the river. The building received publicity when the winner of the first season of The Apprentice, Bill Rancic, chose to manage the construction of the tower.
Trump announced in 2001 that the skyscraper would become the tallest building in the world, but after the September 11, 2001 attacks, the building plans were scaled back, and its design has undergone several revisions. According to the current design, upon completion in 2009 it will be the second-tallest building in the United States after Chicago's Sears Tower, rising above the Empire State Building in New York City and Chicago's current second-tallest, the Aon Center, and third-tallest, the John Hancock Center. It is expected to be surpassed by the Freedom Tower in New York City in 2010 and by the Chicago Spire in 2011. Trump Tower will surpass the Hancock Center as the building with the world's highest residence above the ground until the Spire claims this title.
The design of the building includes, in order from the ground up, retail space, a parking garage, a hotel, and condominiums.The 339-room hotel opened for business with limited accommodations and services on January 30, 2008. April 28, 2008 marked the grand opening with full accommodations and services. A restaurant on the 16th floor opened in early 2008 to favorable reviews for its cuisine, decor, location, architecture, and view.

Design of Modern Highrise Reinforced Concrete Structures
info:
Hiroyuki Aoyama, "Design of Modern Highrise Reinforced Concrete Structures"
World Scientific Publishing Company | 2002 | ISBN: 1860942393 | 300 pages | PDF | 17,7 MB
This book presents the results of a Japanese national research project carried out in 1988-1993, usually referred to as the New RC Project. Developing advanced reinforced concrete building structures with high strength and high quality materials under its auspices, the project aimed at promoting construction of highrise reinforced concrete buildings in highly seismic areas such as Japan. The project covered all the aspects of reinforced concrete structures, namely materials, structural elements, structural design, construction, and feasibility studies. In addition to presenting these results, the book includes two chapters giving an elementary explanation of modern analytical techniques, i.e. finite element analysis and earthquake response analysis.

PERFORM 3D is a highly focused nonlinear software tool for earthquake resistant design. Complex structures, including those with intricate shear wall layouts, can be analyzed nonlinearly using a wide variety of deformation-based and strength-based limit states.
Model data can be imported directly from ETABS and SAP2000. A wide variety of element types are supported, including beams (with panel zones), columns, braces, shear walls (with openings), floor slabs, dampers, and isolators.
Nonlinear analyses can be static and/or dynamic, and can be run on the same model. Loads can be applied in any sequence, such as a dynamic earthquake load followed by a static pushover.
PERFORM 3D provides powerful performance based design capabilities, and can calculate demand/capacity (usage) ratios for all components and all limit states. Performance assessment based on ATC-40, FEMA-356 or ATC-440 is fully automated.
PERFORM 3D output includes usage ratio plots, pushover diagrams, energy balance displays, as well as mode shapes, deflected shapes, and time history records of displacements and forces.
PERFORMANCE ASSESSMENT
PERFORM has built in tools for widely accepted methods of performance assessment
• Deformation and/or strength capacities (acceptance criteria) for components of all types.
• Limit states based on deformation, strength and/or drift.
• Demand-capacity ratios are calculated for all components, and usage ratios for all limit states.
• Performance assessment using static pushover methods, including Capacity Spectrum Method, FEMA 356 and ATC 440 Coefficient (Displacement Modification) Methods, and FEMA 440 Linearization Method. Graphic implementation of all methods, clearly showing target displacement (performance point) and limit states.
• Simple graphic display of limit state usage ratios for dynamic earthquake analyses.
• Results combination for multiple dynamic earthquake analyses, with mean demand/capacity ratios calculated at component level, and simple graphic display of limit sate usage ratios. Simplifies decision making by reducing the results of complex analyses to a few simple graphs.
• Draw structure with members and/or individual plastic hinges colored based on demand/capacity ratio, for both single load cases and load case combinations, to help identify "hot spots".
NONLINEAR MODELING
An unparalleled variety of nonlinear and linear components. Simple properties if you want to keep it simple. More complex properties, as options, if you want sophistication.
• Bars of several types, including buckling bars.
• Beams, columns, braces, shear links.
• Fiber cross sections for beams, columns and walls. Steel, concrete, tension-only and buckling fibers.
• Plastic hinges with PMM Interaction.
• Shear hinges with V-V interaction.
• Fracturing connections.
• Panel zones in beam-to-column connections.
• Shear walls, including coupling beams.
• Squat walls with irregular openings.
• Buckling restrained braces.
• Nonlinear fluid dampers.
• Rubber type and friction pendulum isolators.
• Floor slabs.
• All nonlinear components have similar force-deformation relationships. Elastic-perfectly-plastic or trilinear behavior, with brittle strength loss as an option. FEMA 356 relationship as a special case.
• Optional stiffness and energy degradation under cyclic load. This can be important for earthquake time history analysis.
• P-delta effects in all components, including seismic isolators.
• Account for uncertainty in member properties by specifying upper and lower bounds on strength and stiffness, then vary member strength and/or stiffness at analysis time, without changing the model
• Import model geometry and loads from ETABS and SAP2000
• Full graphic interface
NONLINEAR ANALYSIS
Automated and reliable strategies for static and dynamic analysis, even for complex behavior with brittle strength loss and/or P-delta effects. Handles very large models.
• Nonlinear static pushover, in any direction.
• Nonlinear time history analysis for earthquake ground motions.
• Nonlinear time history analysis for dynamic external forces.
• Modal and/or Rayleigh damping.
• Arbitrary load sequences, such as cyclic push-over or earthquake time-history followed by pushover.
CHECK BEHAVIOR AND DISPLAY RESULTS
Includes a variety of tools to display results, for checking the analysis model and to help you understand the behavior of the structure.
• Time history plots of results, including displacements, velocities, relative and absolute accelerations, member forces, member deformations, drifts and forces on cross sections through any part of the structure.
• Built-in calculation of "floor" response spectra.
• Hysteresis loop plots for inelastic components.
• Graphical energy balance, showing how much energy is dissipated by members of each type.
• Animated deflected shapes, with optional coloring based on member demand/capacity ratio.
• Bending moment and shear force diagrams for beams and columns, including animation.
• Bending moment and shear force diagrams for complex shear walls and shear cores.
• Animated mode shapes.
• Save results to text files for off-line processing (rarely needed).
FOR PERFORM-COLLAPSE
The modeling and performance assessment capabilities of PERFORM 3D, with analysis methods specifically for progressive collapse using the alternate path method.
• Static and dynamic analysis options.
• Catenary effects in floors (true large displacements analysis).
• Automatic calculation and application of forces in removed columns or walls.
• Automatic calculation of vertical masses for progressive collapse analysis.
