Abstract: Abstract The unpredictable out-of-plane buckling of the upper chords is an important problem of half-through truss bridges widely used in many places. Many specifications adopt the theory of elastic stability as a means to obtain… read more here.

Abstract: Steel truss bridges are constructed by connecting many different types of bars (components) to form a load-bearing structural system. Several disastrous collapses of this type of bridge have occurred as a result of initial component… read more here.

DOI: 10.3390/su13031474
Abstract: The condition of joints in steel truss bridges is critical to railway operational safety. The available methods for the quantitative assessment of different types of joint damage are, however, very limited. This paper numerically investigates… read more here.
