In the design of a mechanical structure, we’re interested in finding a general layout of the structure’s supporting frame that best supports some anticipated design loads. Often, the design of such supporting frames are addressed in ad-hoc ways, such as by complicated domain-specific heuristics [TTG05, DG01]. Our project targets the problem of designing a truss–a collection of bars rigidly atta...

Strut-and-tie is a system of forces' distribution in the form of "load-path" connectivity from the applied load point to the support point. Strut-and-Tie Method (STM) has been developed based on simple truss model. STM models represent the load carrying mechanism of a structural member by approximating the flow of internal forces by means of struts representing the flow of compressive stresses ...

A pedestrian bridge is a structure linking or bike path over around major roadway, railway, waterway. The truss (TRB) and the with castellated beam (CBB) are common models of bridge. Past studies have revealed structural behavior TRB CBB, but performances both bridges not yet been comparatively confirmed. This study examined CBB to obtain better model due applied loading. research was started b...

The transverse compression and shear collapse mechanisms of a second order, hierarchical corrugated truss structure have been analyzed. The two competing collapse modes of a first order corrugated truss are elastic buckling or plastic yielding of the truss members. In second order trusses, elastic buckling and yielding of the larger and smaller struts, shear buckling of the larger struts, and w...

Recent advances in the design and construction of large inflatable/rigidizable space structures and potential new applications of such structures have produced a demand for better analysis and computational tools to deal with the new class of structures. Understanding stability and damping properties of truss systems composed of these materials is central to the successful operation of future s...

The classical truss model (or strut-and-tie model) for shear failure of reinforced concrete beams is modified to describe fracture phenomena during failure. The failure is assumed to be caused by propagation of a compression fracture across the concrete strut during the portion of the loading history in which the maximum load is reached. The compression fracture may consist of a band of splitti...

This paper introduces a reliability-based multi-objective design method for spatial truss structures. A multi-objective optimization problem has been defined considering three conflicting objective functions including truss weight, nodal deflection, and failure probability of the entire truss structure with design variables of cross sectional area of the truss members. The failure probability o...
