This work deals with an experimental and numerical approach to determining the differed behavior of compressed wood elements subjected creep loading. An protocol is associated a mechanical model, whose purpose isolate effects from those shrinkage-swelling, while allowing for long duration test be conducted. The based on compression applied five wooden columns disposed in climatic room one year....

a comparison between design codes i.e. aci and aisc-lrfd in evaluation of flexural strength of concrete filled steel tubular columns (cfts) is examined. for this purpose an analytical study on the response of cfts under axial-flexural loading is carried using three-dimensional finite elements with elasto-plastic model for concrete with cracking and crushing capability and elastoplastic kinemati...

it introduced an innovative bioengineering method of consolidating incompact sand by urea-hydrolysis producing calcite cementation under the inducement of urease producing microbe. in the paper it discussed the effects of cementation methods and time on porosity and mechanical properties of microbe-inspired cementing sand columns. method a adopted reaction fluid gravitational permeating and ext...

this paper presents an experimental study on seismic repair of damaged square reinforced concrete columns with poor lap splices, 90-degree hooks and widely spaced transverse bars in plastic hinge regions according to aci detailing (pre.1971) and (318-02) using gfrp wraps. three specimens were tested in “as built” condition and retested after they were repaired by glass fiberreinforced plastic s...

buckling instability is the most important factor at columns failune. icauses large deflection and mostly is analysed by first yield criterion. due fo some difficulties in application of the criterion, soecially in inelastic columns, a new method, namely geometric criterion is introduced in this paper to improve the buckling analysis of real columns. in this research project a number box- secti...

This paper describes the treatment and conservation of an Egyptian wooden coffin box dating back to ca. 1st century. The treatment procedures entailed cleaning, removal of dust and sand, securing severely damaged wooden fragments and damaged resin as well as the use of a suitable gap filler. Studies included wood and microbiological identification. TECHNICAL PAPER 1. Conservation Dept. Faculty ...

Climate change can substantially affect infrastructure performance and safety. In this article, the impact of climate on fungal decay wooden in ground contact is investigated. For purpose, projections three different scenarios are used to assess rate untreated clear wood elements Sweden. The highest increase average observed for four counties located mid-Sweden, i.e. Örebro, Värmland, Västmanla...
