| Summary: | 碩士 === 國立中央大學 === 土木工程學系 === 85 === Abstract The thesis is by means of the scene information
which weight in motion has collected to understand the specific
property of existing truck behavior. The information is analysis
by way at simple support beam and two spans continuous beam in
mechanic to calculate moment and shear of the bridge stresses
distributive situation that is caused by truck load. According
to domestic standard truck load in force of specification, we
can execute the analysis of bridge. Analysis and compare two
being able to get moment ratio and shear ratio and then get to
understand the overload situation of truck at present.
Secondly, compare the results with overseas specification. Then
propose the live load of the bridge design that is suit in
Taiwan and compares it with the bridge an analysis caused by
truck overload, examining its suit situation. This study has
proposed a set of limit design specification based on
probability and reliability to put on the framework synopsis and
primary research. Finally, it suggests to develop an
independence Load and Resistance Factor Design(LRFD)
specification to replace the specification in force gradually.
The aim of the research is order to discuss and appraise the
existing specification objectively. We inquire if it will be
suit to continue using in Taiwan from the opinions of safety and
economy in the future.
