investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
The Fire Performance of Exposed Timber Panels
Cross-laminated timber is increasingly being used in the construction of high-rise buildings due to its simple manufacturing system. In term of fire resistance, cross-laminated timber panels are promoted as having excellent fire resistance, comparable to that of non-combustible materials and to heavy timber construction, due to the ability of thick wood assemblies to char slowly at a predictabl...
متن کاملProbabilistic Evaluation of Eurocode 5 Fire Design Criteria of a Timber Portal Frame
Structural reliability analysis for a three failure were identified for the frame and limit state function was formulated functions were based on the Eurocode 5 design criteria. Uncertainties in the timber material properties were generated from laboratory test results performed on five commonly used timber species in Nigeria, namely Als boonei (Ahun), Triplochiton Scleroxylon (Obeche), Termina...
متن کاملEurocode 5 design in comparison with fire resistance tests of unprotected timber beams
It is generally recognized that heavy timber in fire conditions demonstrates high structural performance. Exposed timber chars which functions as an isolative layer which protects the inner material from heat and loss of load bearing capacity. Char has no significant strength, and therefore, as the char layer grows, the load bearing capacity of the timber member reduces under sustained fire con...
متن کاملFire Safety Engineering – Opportunities and Challenges for Timber Buildings
The combustibility of timber is one of the main reasons that many building regulations strictly limit the use of timber as a building material. Fire safety is an important contribution to feeling safe, and an important criterion for the choice of building materials. The main precondition for an increased use of timber in buildings is adequate fire safety. This paper reviews the opportunities an...
