The paper presents an experimental analysis of timber – framed wall panels with openings, coated with single fibre-plaster boards fastened to a timber frame. The present study is a continuation of the research work realized in the last years in reinforcing of the prefabricated timber-framed wall panels without any openings. The aim of the study presented here was to provide the information abou...

Timber gridshells have become a very popular, efficient, sustainable and beautiful structural application of timber. However, given the slender laths involved in this form of construction, there is concern over the durability of timber for this purpose, and Glass FRP (GFRP) laths have been proposed as a possible substitution. This paper considers this possibility. It goes on to look at the poss...

We construct an intertemporal model of rent-maximizing behaviour on the part of a timber harvester under potentially multi-dimensional risk as well as geographical heterogeneity. Subsequently, we use recursive methods (in particular, the method of dynamic programming) to characterize the optimal policy function, the rent-maximizing timber-harvesting profile. One noteworthy feature of our applic...

This study compares the data available from different satellites having different spatial resolutions to estimate the timber volume. The study comprises mainly the stratification of forest from the input of classified satellite data, measurement of timber volume in the field, extraction of the pixel information for the plots, preparation of a continuous volume map and its comparison among diffe...

Introduction The availability of timber has become an issue across tbc South as supplies from other regions are constrained and as demand for timber continues to grow. Whiie any individual state or landowner will have a small impact on national timber supphes, the avaibbiliv of local timber will have a profound (SERTS), harvest, inventory and growth trc.nds are developed for both nonindustrial ...

Logging has been a much maligned feature of frontier development in the Amazon. Most discussions ignore the fact that logging can be part of a renewable, environmentally benign, and broadly equitable economic activity in these remote places. We estimate there to be some 4.5 +/- 1.35 billion m(3) of commercial timber volume in the Brazilian Amazon today, of which 1.2 billion m(3) is currently pr...

Aggregate timber supply by ownership was investigated for a small region by applying stand-level harvest choice models to a representative sample of stands and then aggregating to regional totals using the area-frame of the forest survey. Timber harvest choices were estimated as probit models for three ownership categories in coastal plain southern pine stands of North Carolina using individual...

In the last two decades, many firms in the U.S. forest products industry have either divested their timberlands to timber investment management organizations (TIMOs) and conservation organizations or converted their corporate structures from C corporations to real estate investment trusts (REITs). All landowners sold smaller timberland tracts for nonforestry uses. Reduced timber supplies from c...

The study was carried out in four community forest user groups (CFUGs) of Sindhupalchok district of Nepal with a view to find out the consumption pattern of forest products especially timber and fuelwood from the community forests (CFs). A set of structured questionnaires was used to collect data from the respondents of the selected CFUGs. Four CFUGs were randomly selected from among those meet...

This paper presents the state-of-the-art of using non-destructive testing (NDT) methods based on elastic waves for the condition assessment of structural timber. Two very promising approaches based on the propagation and reflection of elastic waves are described. While the first approach uses ultrasonic echoes for the testing of wooden building elements, the second approach uses guided waves (G...
