Joints exist widely in tunnel engineering. Studying the deformation characteristics of bolted joint is beneficial for preventing rock mass disasters. To reveal joints, elastic solutions radial joints under compression-shear load were derived, which based on Lame solution mechanics and displacement coordination condition interface between bolt (assuming that at equal). Then, distance from any po...

Often unbraced, the stability of steel storage racks may depend solely on the pallet beam to upright connector and on the stiffness of the base plate to floor connection ([1]). This paper presents experimental results from cyclic tests performed on portal beam to upright bolted moment connections intended for cold-formed steel drive-in and drive-through storage racks. In storage racks, portal b...

In architectural construction, automated robotic assembly is challenging due to occurring tolerances, small series production and complex contact situations, especially in of elements with form-closure such as timber structures integral joints. This paper proposes apply Reinforcement Learning control robot movements contact-rich tolerance-prone tasks presents the first successful demonstration ...

The analytical method for the calculation of properties a bolted joint established by structural Eurocodes proposes T-stub as component characterization tension and compression zones in moment joints. In this article, review state art on is developed, where works developed since it was initially defined, from perspectives formulation, experimentation numerical simulation are summarized discusse...

The use of small-diameter timber in construction has been investigated. The aim of the work is to increase the use of the wood harvested in forest thinning in construction applications. The work has covered a wide range of aspects, from availability of the material to design of the structures. This publication summarizes the results in following areas: availability, dimensions and quality of co...
