Exact first‐ and second‐order analyses for composite beam‐columns with partial interaction subjected to transverse axial loading are presented. General closed‐form solutions the displacement functions various actions in element presented cases. In this paper, loads acting on elements assumed be proportioned accordance their relative stiffnesses so that resultant acts at centroid of transformed cross‐sectional area fully member. Resultant active ensure that, first‐order analysis, uniform...

Multi-storey cross-laminated timber (CLT) buildings are a comparatively recent construction type. Knowledge concerning the performance of CLT regarding prevention disproportionate collapse after unforeseeable events (e.g. accidents or acts terrorism) is not as refined that for concrete and steel buildings. In particular, alternative load paths (ALPs) removal wall panel in platform-framed variants have yet been studied detail. The goal this work was therefore to study ALPs An eight-storey bay...

An apparent analytical peculiarity or paradox in the bending behavior of elastic-composite beams with interlayer slip, sandwich beams, other similar problems subjected to boundary moments exists. For a fully composite beam such end moments, partial model will render nonvanishing uniform value for normal force individual subelement. This is from formal mathematical point view contradiction conditions, which subelement usually assumed vanish at extremity beam. can be explained concept layer....

In this paper, the footfall-induced vibrations in typical timber and lightweight composite floors residential buildings are investigated. The two-floor structures have approximately comparable distributed mass that transverse flexural stiffnesses of two not substantially different. An analysis is carried out to assess floor acceptability structures, based upon derived expressions as well some design codes guidelines such Eurocode. For analysis, cases considered for each structure: a action...

A "file-to-factory" process of computer technology is a way to both maximise efficiency throughout the building process, increase building׳s performance, and be able add interesting architectural possibilities design phase. The authors investigate novel approach that produces set trajectories rather than buildings, yet yields series build-able examples those trajectories. This paper evaluates how this stacked multi-storey timber buildings can incorporated within file-to-factory give rise...

The present study addresses the loading or deformation rate effect on yield loads of nailed timber joints. Four different types joints, which differed with respect to thickness members and angle load grain, were tested. bearing strength wood bending nails also tested in order analytically verify dynamic ultimate capacity All tests run rates from static values up approximately 1 m/s (40 in./s). pilot results show that joints can be expressed terms rate. A logarithmic expression for was...

The vibrations of axially loaded composite beams with partial interaction are considered. equations motion and the pertaining boundary conditions derived from Hamilton's principle. Mainly free — but also forced natural frequencies calculated as a function axial force stiffness between layers. analytical result obtained for eigenfrequencies simply supported beam is taken starting point an approximation subject to other conditions. proposed which has no numerical fitting parameters shown be in...
