2. ABSTRACT This study is conducted by using finite element
analysis and the software used is STAAD.Pro software version 2007.
The model used in this analysis was made up of Glulam beam which is
from timber of Merbau. The dimension of the beam is 500 mm 1500 mm
with a length of span is 50000 mm. Two major analysis involved in
this study which are to investigate the structural and stress
behavior of Glulam beam.
3. INTRODUCTION Mostly in Malaysia, the pedestrian bridges were
built from composite beam, steel beam and reinforced concrete beam.
Glulam is used in construction of structure such as building or
bridges. Glulam used for structural as a green concept towards the
green technology.
4. PROBLEM STATEMENT Costly in manufacturing Contribute to
higher greenhouse gas emission in manufacturing Corrode easily if
no precaution taken Problems faced by conventional bridge such as
steel bridge and reinforced concrete bridge
5. OBJECTIVES To carry out an analysis for the structural
behavior of glulam beam pedestrian bridge To study the stress
effect on the glulam beam pedestrian bridge
6. SCOPE OF STUDY Glulam beam modeled by using STAAD.Pro
Software version 2007 The model supported by fixed and pinned
support and made up from glulam timber type Merbau which is the
specific weight 780 kg/m3 The dimension of the Glulam beam is 500
mm 1500 mm with a length of span is 50000 mm
7. LITERATURE REVIEW Nowadays, in the world including our
country the bridge engineering field is also the popular field
among the other construction field such as the building
construction field. Hence, the designer among the engineer to
design the bridge are the majority required these days refer to the
demanding in building the bridge. (Richard, 2009)
8. METHODOLOGY Formulate Research Objectives Literature Review
Study Data Collection Insert Data Develop Model Using STAAD.Pro
Varification of the Model Analyze the Load on the Model Result and
Analysis of Data Conclusion
9. RESULTS SHEAR AND MOMENT
10. DEFLECTION Max Deflection = 110.564 mm
11. STRESS Max Stress = 4830.3521 kN/m2
12. CONCLUSIONS The structural behavior of Glulam beam analysis
were obtained such as shear, bending moment and deflection. The
stress effect of the beam also obtained. The behavior of the beam
in the analysis most probably depended on the condition of the
loading applied. The maximum deflection at the mid of span was meet
the requirement based on SLS from BD 37/01 condition for live load
was 166.67 mm. The highest stress concentration also at the mid
span of the beam. The shear behavior of the beam also shows results
as expected.
13. RECOMMENDATIONS Getting a better understanding and better
quality of many studies and researches had been done and have to be
done in the future will leading to improvement of its performance.
This research also can undergo a further development study with
some criteria such as by applying other material to glulam such as
carbon fiber or others nanotechnology material that will give
different result on structural behavior and stress effect. Using
other software to do the analysis of glulam beam such as ABAQUS and
others to make comparison between the software and there might be
different with STAAD.Pro software.
