Online and offline monitoring of composite bolted joints under tensile load were investigated using piezoelectric transducers. The relationships between Lamb wave signals, pre-tightening force, the applied tensile load, as well as the failure modes were investigated. Results indicated that S0/A0 wave amplitudes decrease with the increasing of load. Relationships between damage features and S0/A...

The infinite limit of Matrix Theory in 4 and 10 dimensions is described in terms of Moyal Brackets. In those dimensions there exists a Bogomolni’y bound to the Euclideanized version of these equations, which guarantees that solutions of the first order equations also solve the second order Matrix Theory equations. A general construction of such solutions in terms of a representation of the targ...

An experimental investigation is performed on various cold-formed profiled sheets to study the connection behavior of composite deck slab actions using bolted shear connectors. Various profiles like dovetailed (or) re-entrant profiles, rectangular and trapezoidal are used in present investigation. This deals with evaluation parameters such as ultimate load carrying capacity versus deflection, s...

Buku ini lahir dari hasil penelitian Persatuan Gereja-gereja di Indonesia (PGI) terkait kebebasan beragama dan berkeyakinan (KBB) fellowship KBB angkatan ketiga tahun 2021 yang diadakan oleh CRCS Sekolah Pascasarjana UGM. Sebagai program nasional menjadi bagian prioritas RPJMN 2020-2024, moderasi (MB) dipandang dua institusi atas memiliki persoalan serius dalam upaya mengejawantahkan komitmen s...

The nonlinear characteristics of bolted connections are significant importance for analyzing the mechanical performance structures. Iwan model is well-known and has been widely applied; its limitation that it not convenient complex structures with multiple connections. To simplify modeling process, a material force-displacement proposed applied to connection region, which can convert nonlineari...

• 20 specimens were tested with the observation of five kinds failure modes. Angle thickness, horizontal and vertical bolt pitch affected mode connection. Significant plastic deformation appeared in both legs. The prediction formulas for performance connection are proposed. A mechanical model bolted angle is established verified. In this paper, an experimental study was carried out on under uni...

Abstract The aim of this research is to provide an alternative for the conventional design beam‐to‐column connections in building structures. new performed by means Structural Topological Optimization and executed additive manufacturing with steel. Regarding methodology, joint that would be manufactured methods (i.e. welded bolted plates) modelled finite elements first place. Its behavior obtai...

Web of plate girders in bridges are usually reinforced by welded transverse stiffeners inorder to improve their shear capacity. Due to problems associated with field welding and fatigue,welded stiffeners are not suitable for retrofitting existing bridges. Bolted stiffeners are a practicalalternative for strengthening girders that are expected to experience shear stresses in excess of theirdesig...
