Steel Beams with Timber Webs - 1834 Words

INTRODUCTION 1.1 Objective of Proposed Project This project will develop models enabling the structural design of steel beams with timber webs (SBTW). The beams analyzed will have three configurations: an I-Beam type where the steel flange width, bf, is greater than the timber web thickness, tw; a Box Beam configuration where the steel flange width is equal to the timber web thickness; and an Architectural Beam style where the steel flange width is less than the timber web thickness and the steel flanges are totally encapsulated within the timber web. The three beam styles are shown in Figure 1. The physical properties of steel beams with timber webs structures are expected to be highly influenced by the nature of the connection between steel and timber. However, the knowledge of the macro-mechanical properties of glued steel-timber joints is still limited. The work to be performed intends to increase the body of knowledge on this subject. This research study was fomented by the desire to reduce the aspect ratio of long span glued laminated beams. Additionally, the architectural style beam has the possibility of providing the necessary fire protection for the steel while being an extremely aesthetic alternative for exposed structures. The steel beam with a timber web would also be a good candidate for stringer highway bridges with a glulam deck intended for secondary roads. These bridges could be rapidly installed with a minimum of skilled labor decreasing road closureShow MoreRelatedTimber Informative Essay1207 Words   |  5 PagesSRT153  Ã¢â‚¬â€œÃ‚  Building  Materials  Science   Material  Report   Mitchell  Young      Timber  has  been  extensively  used  over  the  past  century  for  many  residential   constructions,  furnishings,  frames,  floorings  and  facades.  It’s  been  a  strong  component  in   architectural  developments  and  with  such  use,  it’s  recognized  in  the  availability,   renewability,  environmental  friendly,  strength,  weight,  price,  and  durability.1  Within   Australia,  90  percent  of  their  housing  frames  are  made  from  timber  due  to  its  sustainability   and  energy  required  to  produce  itRead MoreStructural Use of Timber Essay2878 Words   |  12 Pagesof Timber in Timber Framed Buildings | Civil Engineering Construction 1 | | Adam Roberts | 13/12/2011 | | Table of Contents The History of Timber Framed Construction 1 Modern Timber Frame Construction 2 Multi Storey Timber Frame Construction 5 Benefits and Drawbacks of Timber Framed Construction 7 References 8 The History of Timber Framed Construction Timber framed construction has been â€Å"used in Europe and Asia since the 9th century† (Wikipedia, 2011) .

In Malaysia, the steel has been used especially for the construction of electric tower, industrial building (factory), roof truss, bridge and more.

The diagonal members intersect each other and the horizontal rings at a single node. The members combine to create an element similar to a moment frame. In a Diagrid structure, gravity and lateral loads are resisted by all of the members, creating efficiency and large amounts of structuralRead MoreBuilding Construction8401 Words   |  34 Pagesresistance rating – the quantitatively evaluated fire resistance of the structural components.
