Through the pseudo-static test on the steel truss coupling beams with buckling-restrained brace, the bearing capacity, deformation capacity, hysteresis curve, skeleton curve, ductility, Energy Dissipation and stiffness degradation of such coupling beam are understood. The test results show that the steel truss coupling beams with buckling-restrained brace is characterized by bigger bearing capa...

Recent developments in the area of smart structures indicate that variable geometry / stiffness truss network is of fundamental importance in designing smart transformable structures and systems for space applications. This paper presents the conceptual design and dynamic modeling of a cooperative re-configurabel dual-arm robotic structure called Dual-Arm Cam-Lock Manipulator. The Manipulator i...

A geometry-based rigorous approach to the detection of global and internal mobility of skeletal structures (trusses and frames) is presented. The method is useful for automated design of skeletal structures at the conceptual stage where the overall topology of the structure is known, but no exact detail on geometry and size is available. Such topologies are, for example, those generated by inte...

fundamental engineering concepts through a course in statics. Statics problems usually require the student to draw planar truss and other free-body diagrams (FBDs). In civil and mechanical engineering, visual and spatial thoughts are essential for the correct absorption of fundamental concepts. By relying on visual aids as opposed to only using the verbal channel of acquiring knowledge, the cog...

Reliability is often understood as the probability that a structure will not fail to perform its intended function. In this paper, the general formulation of consistent evaluation of the safety of structures and the associated methods of analysis are reviewed. After the reliability analysis of a cantilever beam is demonstrated, the methodology of reliability-based optimization and the related p...

This paper presents the optimization of the location and feedback gains of active bar in a closed loop control system for stochastic piezoelectric smart truss structures under stationary random excitation. The mathematical model with reliability constraints on the mean square value of the structural random dynamic displacement and stress response is developed based on maximization of dissipatio...

One of the primary objectives truss structure design optimization is to minimize total weight by determining optimal sizes members while ensuring structural stability and integrity against external loads. Trusses consist pin joints connected straight members, analogous vertices edges in a mathematical graph. This characteristic motivates idea representing as graph edges. In this study, Graph Ne...
