Structural bolts have been widely used in prefabricated construction to connect one steel column another due their and structural benefits. In recent years, innovative column-to-column (PCC) connections using normal developed simplify the process of concrete-filled tubular (CFST) columns transfer upper load bottom through bolt-coupler connection. The PCC connection are under compression. Theref...

This is a paper about noncontractive logical systems: systems not closed under contraction. (Contraction is what allows us to conclude that Γ,A⊢B from the claim that Γ,A,A⊢B.)These systems form one family of substructural logical systems: systems that do not impose the full budget of what are called structural rules, or in which there are counterexamples to the structural metainferences associa...

Whole-brain structural connectivity matrices extracted from Diffusion Weighted Images (DWI) provide a systematic way of representing anatomical brain networks. They are equivalent to weighted graphs that encode both the topology of the network as well as the strength of connection between each pair of region of interest (ROIs). Here, we exploit their hierarchical organization to infer probabili...

This paper deals with the performance evaluation of a public transportation system in terms of waiting times at various connection points. The behaviour of a bus network is studied in the framework of Discrete Event Systems (DES). Two possible operating modes of buses can be observed at each connection stop: periodic and nonperiodic mode. Two complementary tools, Petri nets and (max, +) algebra...

A system-based model for fatigue assessment of riveted railway bridge connections, comprising a number of basic components, is presented in this paper. Probabilistic fatigue load spectra are developed through Monte Carlo simulation of train passages over a finite element model of a typical, short-span bridge. Uncertainties arising from loading, resistance and modelling sources are taken into ac...

This paper presents a finite element analysis on the tensile stiffness of steel bolted connections, which are fabricated from thin-walled cold-formed steel strips and members. This type of bolted connection is usually used to assemble the diagonal bracing member in the light steel structure. Unlike the architectural steel structure, thin walled steel bolted connection cannot be simplified into ...

large panel precast structures are analyzed based on the connection rigidity. however, the connections undergo nonlinear and inelastic response, when subjected to seismic loads. thus, to study the actual behavior of structure, the connection nonlinearity should be implemented in the joints. in this paper, three conventional connection types are modeled based on the envelope of their cyclic resp...

The inelastic response of beam-column connections significantly affects the seismic performances of steel frames. Accurate models of beam-column connections are important both in understanding the seismic behavior and in design. An effective approach towards developing accurate models for connections is self-learning simulation, which is presented in this paper. The latter simulation method has...
