چکیده

木造建築における木材需要の経済波及効果の推計において,合板と集成材は用途が異なるため個別に分析されることが望ましいが,既存の産業連関表では合板・集成材部門として集計されている.そこで,合板・集成材部門を合板部門と集成材部門に分割し,産業連関表を拡張した.これによって,合板部門の金額ベースの自給率が集成材部門のそれよりも小さいことから,既存の産業連関表に基づき算出した経済波及効果が合板の需要に対する分析では過大評価となり,集成材の需要に対する分析では過小評価となることが示された.今後,非住宅建築を中心に拡大が期待される木材需要の経済影響評価においては,詳細な部門分類に基づく分析が重要となる.

Computer-aided Design and Construction of Glued Laminated Timber Structure

The paper presents the computer-aided design and construction of a large glued laminated timber structure in Aosta, Italy. The structure was completely computer modelled with in-house developed software, which considers both torsion and curvature constraints of timber. Further proprietary software was used to develop, on a plane, the shape of each timber layer without torsion and curvature . Th...

Feasibility of glued laminated timber beams 1 with tropical hardwoods

11 A feasibility study of glulam was carried out in French Guiana using local wood species. The aim 12 was to determine gluing parameters affording satisfactory behaviour to manufactured glulam in 13 a tropical climate. 14 Three abundant wood species, with special properties, were selected for the study and 15 Resorcinol-Phenol-Formaldehyde resin was used for bonding. Three industrial parameter...

Air-coupled ultrasound inspection of glued laminated timber

A novel air-coupled ultrasound (ACU) 120 kHz normal transmission system enabled successful imaging of bonding and saw cut defects in multilayered glulam beams up to 280 mm in height with a signal-to-noise ratio (SNR) of 40 dB. The main wave propagation paths were modeled; quasi-longitudinal and quasi-transverse modes were coupled in each lamella and the sound field was found to be shifted from ...

Evaluation of a Timber Bridge for the Secondary Road System Using FRP Reinforced Glued-Laminated Girders

One of the goals that the Innovative Bridge Research and Construction (IRBC) program, sponsored by the Federal Highway Administration (FHWA), wishes to achieve through sponsored research projects is the concept of an economical, durable, short-span bridge that reduces construction time. Delaware County, Iowa took a step in that direction through the construction of a 64 ft. long bridge comprise...
