The Behavior Studies of Truss with Eccentric Force
MetadataShow full item record
This research was to study the behavior of trusses which subject to the eccentric force. The trusses are tested, and load action and deformation of trusses are observed with eccentric distance of 0, 4, 8, 12 and 16 centimeter in order to compare with the results from finite element method. The results of eccentric trusses show equivalent stiffness value less than the case of noneccentric trusses. The maximum load value at the center length of eccentric trusses 4, 8, 12 and 16 centimeter decrease 15.3, 51.1, 66.7 and 76.6 percent respectively when compare with noneccentric trusses. Moreover, test results found that the eccentric trusses have more toughness than those from non-eccentric trusses. By observation the deflection at center length of eccentric trusses 4, 8, 12 and 16 centimeter, the deflection at maximum load is increasing 75.76, 155.69, 293.11 and 414.09 percent respectively when compare with non-eccentric trusses. From comparison results with analysis results by finite element program, it is seen that the analysis results has a more equivalent stiffness than the results from experiments average 29.6 percent.
