This paper presents an interactive framework for the design of truss structures with incorporation of the subjective influence of user feedback in the design process. In the devised framework, the truss chords are described using Non-Uniform Rational Basis Splines (NURBS), a representation typically used in computer aided design (CAD) for describing free-form geometry. This allows for a conveni...

Abstract Three typical elastic problems, including beam bending, truss extension and compression, two-rings collision are simulated with smoothed particle hydrodynamics (SPH) using Lagrangian Eulerian algorithms. A contact-force model for collisions equation of state pressure arising in colliding bodies also analytically derived. Numerical validations, on the corresponding theoretical models, c...

The outrigger arm system and belt truss with braced core in the center of the structure surrounded by belts truss, is an efficient and reliable system for high-rise buildings against severe lateral forces such as earthquake and wind. The purpose of this research is investigating the outrigger arm system and belt truss with the braced core under lateral loads. Another purpose of this research is...

The section deformation distribution of reinforced concrete components is nonlinear due to the size effect. Existing analysis models such as plastic hinge and truss element are based on plane cross-section assumption. cannot be accurately simulated. Therefore, in this paper, non-planar strain functions sections established. law influence geometrical characteristics load distributions beam ends ...

In this article on increasing the efficiency of steel combined structures, tasks rational design, regulation and control structural parameters elements, use steels with increased mechanical properties are considered. It is shown that for a six-span stiffening girder truss elastic supports, which operates under distributed load, moment 72 times smaller than single-span beam. suggested to high-st...

A small, light, ball-joint device called PinFix, which can instantly convert a simple percutaneous cross pin fracture fixation system into a rigid external fracture fixation system based on truss structure, was developed. The purpose of this study was to compare the mechanical load and breaking strength of this truss-structure-based fixation system to that of the conventionally used external ca...

This paper investigates the experimental and analytical behaviour of beam-column joints that are subjected to a combination torque, flexural direct shear forces, where different Carbon Fibre Polymer (CFRP) strengthening wraps have been applied only beam. These wrapping schemes previously determined by research community as an effective method enhancing torsional capacities simply supported rein...

This paper presents a comparative study of two indirect solution representations, a generative and an ontogenic one, on a set of well-known 2D truss design problems. The generative representation encodes the parameters of a trusses design as a mapping from a 2D space. The ontogenic representation encodes truss design parameters as a local truss transformation iterated several times, starting fr...
