This way, we can ensure quick response joists spanning over thirty feet. time, quality, and consistency to our customers. These straight web members allow an easier weld with the chord members. PAINT Canam’s standard shop paint is GRAY primer. Other primer colors may be available at some locations. The typical shop applied primer that is used to coat steel joists and joist girders is a dip-applied, air dried paint. The primer is intended to be an impermanent and provisional coating which will protect the steel for only a short period of exposure in ordinary atmospheric conditions. Since most steel joists and joist girders are primed using a standard dip coating, the coating may not be uniform and may include drips, runs, and sags. Compatibility of any coat- ing, including fire protective coatings, applied over standard shop primer shall be the responsibility of the specifier and/or painting contractor. The primer coating may require field touch-up/repair. The joist manufacturer shall not be responsible for the condition of the primer if it is not properly protected after delivery. 7 MEP-Cat.

Tel: 668-6514-3075. E-mail: [email protected], [email protected] Received: May 3, 2017 Accepted: June 29, 2017 Online Published: July 25, 2017 doi:10.5539/ass.v13n8p103 URL: https://doi.org/10.5539/ass.v13n8p103 Abstract The objectives of this research were to study and design packaging, test its efficiency, and determine the satisfaction levels of consumers with the structure and graphic design of a craft wooden boat model packaging produced from corrugated board using natural extract to prevent termites. Data collection was conducted using focus groups of producers and consumers. Data was then summarized and used for the design and creation of the model packaging. Suggestions from experts were applied to improve the packaging of the craft wooden boat model; its preventive efficiency was then tested and the satisfaction of consumers was assessed. The results of the package structure test showed that bursting strength was 8.66 kgf/cm2, edge crush test was 3.86 kg/cm and drop height was 762 mm, which reaches standards ASTM D 774, ISO 3037 and ASTM D 5276, as well as helping prevent termites from biting. The size and design were portable and suitable to be displayed for sale.

Symp. Cambridge, 2013, (S.J. I’Anson, ed.), pp 321–357, FRC, Manchester, 2018. DOI: 10.15376/frc.2013.1.321. VARIABILITY, NON- UNIFORMITY, AND COMPLEXITY: FROM PRODUCT TO PROCESS Tetsu Uesaka Fibre Science and Communication Network (FSCN), and Department of Chemical Engineering, Mid Sweden University, SE- 851 70, Sundsvall, Sweden 1. INTRODUCTION The variability in process and product is part of our life in the industry. For example, in the headbox jet speed and temperature are constantly changing at different frequencies; cross-machine direction elastic stiffness has a typical inverse-smile pattern across the paper machine width; qualities of pulp bale often vary from one shipment to the other. For many years, the industry has been tackling this problem in different unit processes. Particularly in today’s competi- tive market, achieving consistency and uniformity is a necessary condition for staying in the market. Accordingly the subject has been heavily investigated in process control area in terms of control methods (adaptive control, multi- variable control, and expert system), sensor developments, and process modeling and simulation. (A comprehensive review of contemporary process control is provided in [1–2].) This review paper deals with the same subject but from a slightly different angle, i.e., performance perspective. In the beginning, it may not be obvious why performance problems are those of variability and non- uniformity. However, this problem almost always emerges as a central theme at the end.

  • Chapter 2: TRUSS and ROOF TERMINOLOGY
    Chapter 2: TRUSS AND ROOF TERMINOLOGY APEX: The highest point on a truss where the sloping top chords meet (Figures 3, 4 & 6). AXIAL FORCE: A push (compression) or pull (tension) acting along the length of a member. Usually measured in Newtons (N) or kiloNewtons (kN). (Figure 18) AXIAL STRESS: The axial force acting at a point along the length of a member, divided by the cross- sectional area of the member. Usually measured in MegaPascals (MPa) or Newtons per square millimeter (N/mm2). (Figure 18) BARGE BOARDS: Trim boards applied to gable ends of buildings. (Figure 2 & 10) BATTENS: Small-section timber members – usually 36x36 (See SANS 1783-4) spanning between trusses, connected to the top of the top chord of the truss and usually supporting a roof covering of tiles or slates (Figure 4). BATTEN CENTRES: The distance between centre lines of battens, measured along the slope of the top chord (Figure 8). BAY LENGTH: Also called PANEL LENGTH. In a truss this refers to the horizontal distance between the centres of joints or nodes in either the top or bottom chord. In a roof, it refers to the space between trusses, e.g. a single or double truss spacing where bracing occurs. (Figure 7 & 8) BRACED BAY: The space between 2 or more trusses in a roof section where bracing is positioned (Figure 2) BEAM: A solid or composite timber lintel that usually supports trusses or rafters. (Figure 11) BEAM POCKET: A void deliberately set into a wall to allow a beam, truss horn or floor truss to bear on the wall.

What is a truss? A “truss” is formed when structural members are joined together in triangular configurations. The truss is one of the basic types of structural frames formed from structural members. A truss consists of a group of ties and struts designed and connected to form a structure that acts as a large span beam. The members usually form one or more triangles in a single plane and are arranged so the external loads are applied at the joints and therefore theoretically cause only axial tension or axial compression in the members.
