Book Synopsis Effects of Thermal Shrinkage on Built-up Roofing by : William C. Cullen
Download or read book Effects of Thermal Shrinkage on Built-up Roofing written by William C. Cullen and published by . This book was released on 1965 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of thermal movement of bituminous built-up roof membranes are related to some common failures of built-up roofing observed in field exposures.A procedure for determining the amount of thermal movement of built-up membranes is described.Data are given for the thermal movement of various bitumens and reinforcing felts used in the con * struction of built-up roofs and for the composite membranes over a temperature range construction of built-up roofs and for the composite membranes over a temperature range of +30 to -30F.The data obtained are related to field experience and suggestions are presented which will prove beneficial in reducing the incidence of built-up failure due to thermal movement.(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 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 Investigation of the Hydraulics of Horizontal Drains in Plumbing Systems by : Robert S. Wyly
Download or read book Investigation of the Hydraulics of Horizontal Drains in Plumbing Systems written by Robert S. Wyly and published by . This book was released on 1964 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results are reported from an investigation of the hydraulics of flow in experimental apparatus simulating nominally horizontal simple and branching drains of plumbing systems. The data are correlated with limited findings in an earlier, unpublished NBS study the results of which have been utilized in current plumbing codes. The need for further research is pointed out, particularly in relation to hydraulic performance of drain systems as affected by steep slopes, drain storage volume, energy losses at stack bases, attenuation of water depths and discharge rates in long drains, and large drain diameters.
