      <title>Rough Surface Finishing of Stone-Faced Sandwich Panels Using High Pressure Waterjet</title>
      <link>https://trid.trb.org/View/1216004</link>
      <description><![CDATA[The natural stone veneer used to clad sandwich panels needs to be less than 1 cm thick to ensure a lightweight structure. However, diminishing the thickness reduces slab strength, which is important when the stone is to be rough finished. Thus, traditional techniques such as bush-hammering and flaming are unfeasible for these veneers. The main aim of this study was to investigate the possibility of using high-pressure waterjet technology for stone veneer finishing. First, the characteristics of the stone were determined (origin, petrography chemistry, strength). Suitable combinations of waterjet operating parameters (pressure, traverse speed, distance between successive passes) were then tested to determine optimal results, in terms of both performance and aesthetics. The investigation demonstrated the success of this technique for processing large slabs (100 cm ×  200 cm), with thickness of just 3 mm, thus also overcoming the problems involved in maneuvering heavy slabs with thickness of more than 2 cm. Surface roughness analysis of the treated stone showed it to compare favorably with competing technologies, with the advantage that waterjet maintains the natural color of the rock. Finally, some economic considerations are discussed.]]></description>

      <title>Experimental Tests of Notched and Plate Connectors for LVL-Concrete Composite Beams</title>
      <link>https://trid.trb.org/View/1090751</link>
      <description><![CDATA[This paper reports the experimental results of symmetrical push-out tests performed on notched and toothed metal plate connectors for laminated veneer lumber (LVL)-concrete composite floor systems. The characteristic shear strength and slip moduli were evaluated for three types of connectors: (1) a 300-mm-long rectangular notch cut in the LVL joist and reinforced with a 16-mm-diameter lag screw; (2) a triangular notch reinforced with the same lag screw; and (3) two 333-mm-long toothed metal plates pressed in the lateral surface of two adjacent LVL joists. The shear force versus relative slip relationships are presented together with analytical prepeak and postpeak approximations which can be used to carry out nonlinear finite-element analyses of LVL-concrete composite beams. The failure mechanisms of the notched connections are also discussed. Analytical design formulas for shear-strength evaluation of notched connections derived in accordance with New Zealand Standards and Eurocodes are proposed based on four possible failure mechanisms. Good approximation was found if a slight modification of the Eurocodes formulas is introduced.]]></description>

      <link>https://trid.trb.org/View/708190</link>
      <description><![CDATA[This Code in this document covers the design and construction of masonry structures while the Specification is concerned with minimum construction requirements for masonry in structures. Some of the topics covered in the Code are: definitions, contract documents; quality assurance; materials; placement of embedded items; analysis and design; strength and serviceability; flexural and axial loads; shear; details and development of reinforcement; walls; columns; pilasters; beams and lintels; seismic design requirements; glass unit masonry; and veneers.  An empirical design method and a prescriptive method applicable to buildings meeting specific location and construction criteria are also included.  On the other hand, the Specification covers subjects such as quality assurance requirements for materials; the placing, bonding and anchoring of masonry; and the placement of grout and of reinforcement. The Specification is meant to be modified and referenced in the Project Manual.  Since the Code is written as a legal document and the Specification as a master specification required by the Code, the two commentaries present background details, committee considerations, and research data used to develop the Code and Specification.]]></description>

      <title>LINED VENEER IN TRAFFIC SIGNS</title>
      <link>https://trid.trb.org/View/278217</link>
      <description><![CDATA[The bulk, about three-quarters of traffic signs are manufactured of weather-resistant lined birchwood veneer. These products have been used in Finland for about ten years and the experience is generally positive.  This price/durability ratio is highly comparable to other products suited to traffic signs. Veneer traffic signs have been investigated by forest products laboratory in technical research centre of Finland for more than four years.  The article is based on test results and other material related to the investigation.  In the first years of use the traffic sign film showed some cracking, which was not due to the type of lined veneer used but was linked with other factors of the manufacturing process.

      <title>DESIGN, FABRICATION, TESTING, AND INSTALLATION OF A PRESS-LAM BRIDGE. FOREST SERVICE RESEARCH PAPER</title>
      <link>https://trid.trb.org/View/150665</link>
      <description><![CDATA[Parallel laminated veneer (PLV) products are manufactured by adhesive bonding of rotary-peeled veneer. It has been estimated that a production line PLV process could convert green logs into a finished structural laminate in less than an hour. Press-Lam, a PLV product under investigation at the U.S. Forest Products Laboratory, has exhibited decreases in variability of mechanical properties and increases in chemical preservative penetration and retention when compared to solid-sawn lumber. A prototype highway bridge constructed entirely of Press-Lam has been erected by the Virginia Department of Highways and Transportation. This bridge was field tested to its AASHTO HS-20 design load. Preliminary allowable stresses were determined by data obtained from destructive laboratory tests on 18 full-scale stringers and 6 sections of decking made from Douglas-fir Press-Lam. In the face of dwindling supplies of large structural timbers, PLV products are attractive alternatives for exposed structural applications. (Author)]]></description>
