Book Synopsis Thermal-shock Resistance for Built-up Membranes by : William C. Cullen
Download or read book Thermal-shock Resistance for Built-up Membranes written by William C. Cullen and published by . This book was released on 1967 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resistance of bituminous built-up roofing membranes to thermally induced forces is considered in terms of their strength properties such as breaking load in tension, modulus of elongation and apparent linear thermal expansion coefficient.The development of a Thermal-Shock Resistance Factor is described and values are given for three bituminous built-up membranes at temperatures of - 30F (-34.4C), 0F (-17.8C), 30F (-1.1C) and 73F (22.8C).The apparent relation between the values obtained in the laboratory and the observed performance of roofing membranes in service is considered.The utilization of the Thermal-Shock Resistance Factor in the reduction of potential failures of bituminous built-up roofing membranes in service from thermally induced forces is also discussed.(Author).

Book Synopsis Laboratory-field Comparisons of Built-up Roofing Membranes by : Thomas H. Boone
Download or read book Laboratory-field Comparisons of Built-up Roofing Membranes written by Thomas H. Boone and published by . This book was released on 1968 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The values of breaking load, elongation and thermal expansion of nine bituminous built-up membranes prepared by roofing contractors under field conditions and by technicians in the laboratory were measured at sub-freezing temperatures.The data indicated that the field-prepared specimens agreed favorably with laboratory-prepared specimens, although the samples from the field frequently reflected higher values for thermal-shock resistance than did their laboratory-prepared counterparts.The higher values were attributed to the smaller amounts of bitumen used between the plies of the field specimens.The results appeared to support the validity of the application of the 'strength-thickness rule' to bituminous built-up membranes.(Author).

Book Synopsis Preliminary Performance Criteria for Bituminous Membrane Roofing by : Robert G. Mathey
Download or read book Preliminary Performance Criteria for Bituminous Membrane Roofing written by Robert G. Mathey and published by . This book was released on 1974 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the first in a series of publications on performance criteria for built-up roof membranes. The development of a performance approach to bituminous built-up roof membranes is described and preliminary performance criteria are recommended. A number of test methods have been developed in order to obtain data to evaluate roofing membranes against the recommended criteria. Twenty attributes that effect the performance of roof membranes under service conditions are identified and laboratory tests are described for measuring the engineering properties of the membrane that pertain to many of these attributes. A level of performance is recommended for nine of the identified performance attributes.

Book Synopsis Fire Resistance of Steel Deck Floor Assemblies by : Harry Shoub
Download or read book Fire Resistance of Steel Deck Floor Assemblies written by Harry Shoub and published by . This book was released on 1967 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests were conducted to determine the resistance to fire of welded steel plate and beam floor assemblies with various conditions of floor covering on the plates, and ceiling protections beneath the beams. The trials included fire exposures from the burnout of combustible materials ranging from 10 to 40 lb/sq ft on the floor surface as well as standard fire endurance tests in which the ceiling of the structure was exposed to fire. The results of the tests indicated that the use of steel floor structures was practical from considerations of fire safety. For the test conditions established, fire exposure on top of the floor did not heat the structural steel supporting members sufficiently to cause load failure or collapse, and did not produce untenable conditions in the room below. In tests involving fire exposure to the underside of floors, the fire endurance times, based solely on heat transmission criteria, ranged from 1 hr 24 min to over 4 hr. Temperature levels attained by the structural members and deflection of the floor assemblies are also reported. (Author).
