WHY VERSATUBE. VersaTube manufactures Do-It-Yourself steel building kits. No cutting, welding or heavy equipment required and every framing component can be lifted with average human strength and assembled with common tools.

The World Trade Center towers had an innovative "tube" design, with a perimeter support structure joined to a central core structure with horizontal floor trusses. The final complex consisted of seven buildings, dominated by the twin 110-story towers rising more than 1,360 feet (415 meters) above an ...

Mar 21, 2018· Tube-in-tube . This system is also known as 'hull and core' and consists of a core tube inside the structure which holds services such as utilities and lifts, as well as the usual tube system on the exterior which takes the majority of the gravity and lateral loads.

stiffness and stability to the framed-tube system in addition to supporting the floor loads. The first major structural subsystem was the exterior framing, which was a vertical square tube that consisted of 236 narrow columns, 59 on each face from the 10th floor to the 107th floor (Figure 3).

Structural tubing per ASTM A500 is tubing produced and used for structural applications. Standard strength requirements of the tube help dictate applications for which certain tubing is most appropriate. Structural tube is often referred to as hollow structural sections or HSS.

The Design Capacity Tables have been prepared for DuraGalUltra angles, channels and flats in accordance with AS/ NZS 4600:2005 Cold-formed steel structures. For ease of use, a similar but slightly modified format to the ASI Design Capacity Tables has been adopted. The design basis of the tables is contained in Appendix A.

interactive structures, using the shear-flexural cantilever analogy. The rigid outrigger approach was utilized to develop a program called Outrigger Program to analyze multi-outrigger braced tall buildings. In addition, a program called Frame Tube was developed which allows analysis of single and quad-bundled framed tube structures.

the development of seismic design recommendations. For example, nonlinear analysis is central to the FEMA P695 procedure for quantifying seismic performance factors (FEMA 2009). Fiber based beam finite elements are well suited to concrete-filled steel tube (CFT) frame structures. Such models provide accurate results as well as

Sep 20, 2013· Bundled Tube Structural System 1. Bundled tube structural system By Umer Farooq Presentation on 2. One of the most efficient structural systems against heavy wind loads is the bundled tube structural system The first person to implement the bundled tube structural system was Fazlur Rahman Khan from Dhaka, Bangladesh with the design of the

SPECIFICATION FOR THE DESIGN OF STEEL HOLLOW STRUCTURAL SECTIONS vii PREFACE The AISC Load and Resistance Factor Design (LRFD) Specification/or Structural Steel Buildings is intended to cover the common design criteria in routine office practice. Accordingly, it is not feasible to also cover the many special and unique

Chapter 5, Structural Steel Design 5-3 5.1 INDUSTRIAL HIGH-CLEARANCE BUILDING, ASTORIA, OREGON This example features a transverse steel moment frame and a longitudinal steel braced frame. The following features of seismic design of steel buildings are illustrated: 1. Seismic design parameters, 2. Equivalent lateral force analysis, 3.

This maximizes the effectiveness of the perimeter tube by transferring some of the gravity loads within the structure to it, and increases its ability to resist overturning via lateral loads. History. By 1963, a new structural system of framed tubes had appeared in skyscraper design and construction.

Excavation work began for Burj Khalifa the tallest skyscraper in the world in January 2004 and over the years, the building passed many important milestones to become the tallest man-made structure the world has ever seen. In just 1,325 days since excavation work started in January, 2004, Burj Khalifa became the tallest free-standing structure in the world.

The design process encompasses the architectural design, the development of the structural concept, the analysis of the steel structure and the verification of members.Steel solutions are lighter than their concrete equivalents, with the opportunity to provide more column-free flexible floor space, less foundations and a fast, safe construction programme.

Torsion in Structural Design 1. Introduction 1.1. Problems in Torsion The role of torsion in structural design is subtle, and complex. Some torsional phenomena include (a) Twist of beams under loads not passing through the shear center (b) Torsion of shafts (c) Torsional buckling of columns (d) Lateral torsional buckling of beams
