Ninety walls of 10 different types of masonry construction were tested under various combinations of vertical and transverse load. It is shown that the effect of vertical load and wall slenderness on transverse strength can be predicted by rational analysis. The analysis is based on established theory which has been extended to account for the properties of masonry. Similar methods of rational analysis have been adopted for the design of steel structures and are presently being considered for reinforced concrete structures.

Immediately following the San Fernando, California earthquake (February 9, 1971), a four-man team from the Building Research Division of the National Bureau of Standards' Institute for Applied Technology, surveyed the damage to buildings and other structures. This report is based primarily on the data gathered during the survey but includes some data provided by other agencies and individuals.Based on study of these data and observations made during the survey, recommendations are made pertaining to the improvement of building and other structural design and construction practices.(Author).

The weather resistance of 192 porcelain enameled panels representing 14 enamel types was evaluated after being exposed for 30 years at Washington, D.C.A direct correlation was found between the acid resistance and weather resistance of the enamels tested.The porcelain enamel protected the base metal from corrosion if the initial coverage was complete.Similar evaluations and findings were made on 58 panels representing 13 enamel types that were added to this test in 1947.(Author).

A series of structural evaluation tests performed on components and materials intended for use in one of the Operation BREAKTHROUGH housing systems is described. Four samples of steel faced, paper honeycomb, sandwich panel material and four full size prototype roof panels were evaluated. The samples of sandwich panel material were used to evaluate the variability of panel material properties and the effect of aging on tensile and shear strength. The roof panels were used to determine the behavior in service considering the effects of adverse environmental conditions on ultimate strength and mode of failure. In addition, the performance of one panel under sustained loading was evaluated. (Author).
