FYP 1 Analysis of structural behavior of glulam beam ppt NLCA punye

  1. 1. Mostly in Malaysia, the pedestrian bridges were built from composite beam, steel beam and reinforced concrete beam.They are usually the fastest way and easily to built however they also can contribute to unsustainable beam and no longer long lasting pedestrian bridges such as the reinforcement of the concrete which is the steel without difficulty to corrode and damaged Glulam or glue laminated timber is used in construction of structure such as building or bridges instead use of steel or reinforced concrete. Glulam used for structural as a green concept towards the green technology. It also suitable for sustainable development for pedestrian bridge because it has higher tensile strength compared to the steel
  2. 2. There are some disadvantages of the conventional bridge such as steel bridge and will contribute to higher greenhouse gas emission in manufacturing the steel to produce the beam. They also are costly in manufacturing and to make sure the bridge are long- lasting. They also can corrode easily if no precaution action will be taken Hence, the glulam bridge beam can overcome the disadvantages of the conventional bridge by reducing the cost in manufacturing because glulam come from natural sources. Glulam are made from wood which is renewable resources because when cutting the tree it can be planted again. It also can reduce the greenhouse gas emission in manufacturing. The grip of the pedestrian subjected to the bridge is focused in this study. The stress due to vertical live loading will cause the Glulam beam fail if it reaches to elastic limit
  3. 3.  To carry out a modeling analysis of the structural behavior of Glulam beam of 50 metre pedestrian bridge subjected under vertical live load based on BD37/01 using finite element software namely London University Stress Analysis System and also known as LUSAS

  5. 5.  Bridge is a structure that built for people or vehicles to cross over the barrier for instance the road, the river, and the railway. Bridge also can be changeable in its designing and can be design based on the function of the invention of the bridge (P. J. S Cruz, 2009).
  6. 6.  Pedestrian bridge also namely as foot bridge is built for the people to walk on such as to cross over the congestion of the traffic and without disturbing the traffic and crossing the road safely (Rhode-Barbarigos, 2010).
  7. 7.  From the previous period of 37 years before, there are many uses of timber for pedestrian bridge are built for main road and municipal travel road. (Stefano Battocchi and Andrea Polastri, 2006).
  8. 8.  In the engineered wood construction, glue laminated timber contribute in redefining the potential. The structural usefulness of a renewable resources such as wood can be optimizes by the glulam as an engineered wood product. The members of the glulam are consisted of the individual pieces of dimension lumber. Glulam are tougher than steel and it is meaning that beam for glulam can has long distances of the span without maximal need for the support at the intermediate. (John Blaustein, 2008).
  9. 9.   The loadings of the bridge are usually design based on Eurocode 5 or BD 37/01, which is the design manual for roads and bridges. In our country, the designing of the structural for timber is based on Malaysian Standard (MS 544).
  10. 10. Author Year Title Objective Findings Stefano Battocchi & Andrea Polastri 2006 Pedestrian timber bridges with glulam beams and LVL deck To have a confirmation that the simplified schemes adopted in hand calculations are correct and on the safe side and to make a realistic analysis of the mechanical response either of the entire structures or its individual components, in the various significant load combinations The effects of the concentrated load that acts over the deck of the bridge cannot be solved by simplified hand calculations, and finite element models must be developed to get a correct solution. Baidar Bakht 1988 Load distribution in laminated timber decks To review the current methods and where appropriate, propose new ones for analyzing the load distribution effects in transverse laminated decks subjected to concentrated wheel loads Improvement in load distribution characteristics in laminated decks, due to either gluing or prestressing the laminates together can be quantified readily by using the simplified methods
  11. 11. Nominal pedestrian load based on BD37/01 as follow : For loaded lengths in excess of 36m , k × 5.0 kN/m2 where k is the nominal HA UDL for appropriate loaded length (in kN/m) × 10 For loaded lengths of 36m and under, a uniformly distributed live load of 5.0 kN/m2 Displacement due to temperature : ∆L = ɑ (∆T) L Where : L = Span length ɑ = Coefficient of thermal expansion (∆T) = Changes in temperature
