Tall Buildings - Structural design of concrete buildings up to 300 m tall
Size: 3.22 MB | Format:PDF | Quality:Original preprint | Publisher: the fib and MPA The Concrete Centre (UK) | Year: 2014 | pages: 164 | ISBN: 978-2-88394-113-7
fib Bulletin No. 73
Abstract:
fib Bulletin 73: Tall Buildings is the result of a collaboration between the fib and MPA The Concrete Centre (UK).
Task Group 1.6 High-rise buildings, within fib Commission 1: Structures, was drawn together with a mandate to write about the experience and know-how pertinent to the development, design and construction of tall concrete buildings. The group’s findings are presented in this state-of the-art report.
Tall buildings are a unique challenge to engineers, even to those with extensive experience of low-rise structures. The bulletin explains the critical interfaces with other professionals, for example architects, building services engineers, façade and lift specialists, geotechnical engineers and wind specialists, highlighting how these parties interact with engineers and can influence and guide the development of the structural solution.
The key factors in choosing the most appropriate structural system are discussed. The bulletin covers the criteria used to select the most economical structural elements including the foundations, the vertical elements and the floor slabs. Examples of common construction methods are presented and their effects on the structural engineering design are discussed. Tall buildings can undergo significant deformation during their construction and service life. These movements need to be understood by the designer and potentially compensated for in the design and during construction.
One of the main particularities of the design of tall buildings is the dominance of the lateral loading from wind and seismic actions. The bulletin provides a discussion of these important topics and sets out the current approach taken by experienced engineers. Designers of tall buildings also need to understand the dynamic behaviour of the structure and confine the motion of the building to within acceptable limits. Approaches to damping and dynamic performance are discussed and guidance provided on the appropriate occupant comfort limits.

Advance Steel detailing software helps accelerate design, steel detailing, steel fabrication, and steel construction—built on the familiar AutoCAD platform.
Key enhancements for Advance Steel 2016 include:
- Steel Modeling: Scalability & Performance Improvements – Helps to navigate more efficiently in a model by quickly isolating selected elements in a work area to be displayed in the current visual style, while the other elements get a much lower LOD (beams axis shown only). This enhanced feature helps improves performance when working with complex models.
Enhancement helps improve performance when working with complex models.
- Steel Modeling: Weld definition properties enhanced – Representing specific weld characteristics in a DWG file used for fabrication can be a time-consuming, tedious task. Enhancements now help users to define weld properties directly [e.g. effective throat or root opening], or opt to have them set automatically when using the automatic steel connections feature. The resulting ISO standards-compliant weld symbols are displayed automatically on drawings; and specific preferences may then be easily adjusted in the DWG file.
Specify weld properties in the model and get them being displayed more accurately on drawings.
- Interoperability: Status tracking information – Helps to easily round-trip model information with MIS software thanks to a bidirectional link. This enables the updating of a model with the current status information from fabrication to shipping. Elements can then be colorized in the 3D model based on these updated status. These features help facilitate an integrated steel fabrication management process.

Author: Amir N. Nahavandi, George V. Catanzaro | Size: 3.06 MB | Format:PDF | Quality:Scanner | Publisher: ASCE Journal of the Hydraulics Division | Year: January 1973 | pages: 18 | ISBN: 0044796X
A new matrix method is developed for the steady-state and transient analyses of incompressible flow networks. It is shown that the branch pressure drop versus nodal pressure, nodal continuity, and branch momentum equations can be expressed in matrix form for networks with any arbitrary configuration. These equations are solved simultaneously to obtain explicit relations for the unknown nodal pressures and branch mass flow rates. This new technique is applied to the analysis of a water distribution network. To ascertain the accuracy of the solution, a numerical stability and convergence analysis is performed which provides an estimate for the upper bound of time increment needed for a stable and convergent numerical integration. The transient and steady-state behavior of incompressible flow networks with arbitrary configurations having nodal sources and sinks as well as branch transducers are determined by the time-integration of the network dynamic equations with a comparatively smaller computer running time.
