Condition Assessment of the Timber Structures of a Century-Old Industrial Building Using a Nondestructive Inspection Procedure Xiping Wang1,a, Marko Teder2,b, and James Wacker1,c 1USDA Forest Products Laboratory, One Gifford Pinchot Drive, Madison, WI 53726, USA 2Dep. of Rural Building, Inst. of Forestry and Rural Engineering, Estonian University of Life Sciences, Kreutzwaldi 5, Tartu 51014, Estonia axwang@fs.fed.us, bmarko.teder@emu.ee, cjwacker@fs.fed.us Keywords: Inspection, microclimate, resistance micro-drilling, stress wave timing, timber structure Abstract.
The purpose of this investigation was to conduct an in situ physical condition survey of the large timber members using a nondestructive testing procedure and provide the facility engineers a fair assessment of the true physical conditions of the structure upon which a rational and cost-effective repair plan can be established.
The scope of the in situ physical inspection was limited to the areas that were under concern and specified by the facility engineers.
A combination of visual, hammer sounding, stress wave timing, and resistance micro-drilling techniques were used to inspect the timber members in the concerned areas specified by the facility engineers.

Visual Implement of Virtual Reality Tour based on VRML Jianbing Xiahou1, a, Jintong Rao2,b, Yuan Li2,c, Yao Yin1,d 1 School of Software, Xiamen University, Xiamen 361005, china 2 School of Architecture and Civil Engineering, Xiamen University, Xiamen 361005, china ajbxiahou@xmu.edu.cn, braojintong@xmu.edu.cn, cliyuan79@xmu.edu.cn,dyaoable@gmail.com Keywords: VRML, Polyline, Tour Abstract: In this paper, a visual solution is presented about virtual reality tour of Web3D based on VRML.
As shown in Figure 3, combining engineering practice, the cube in the center expresses polyline vertices through visualization methods, while the three arrows express the directions of three axes’ movements through visualization methods.
The virtual reality system has been applied in a number of projects, and has been applied with great practical significance, but also greatly improves engineering efficiency.
