The use of computer programs for the layout planning of buildings requires some form of input data defining the relationships between activities. This data may be given on a derived rating scale (subjective data) or in terms of measured movement interchange (continuous data).
The collection of continuous data can be a time consuming and costly process. Experimental work using a generative (construction-type) layout planning program identifies the effects of varying the precision of continuous data and indicates that more approximate forms than those presently employed may yield acceptable layout solutions.

Paper presents prediction of probability of failure of prestressed concrete beams. Probable strengths of basic materials used in the beam are generated as random variables subject to code specifications and the probability of failure of the beam is obtained through explicit formulation. Probability of failure of beams designed by Indian code of practice and code of American Concrete Institute is illustrated through a set of examples. It is found that the probability of failure of a prestressed concrete beam is very sensitive to variation of steel and less sensitive to the variation in the strength of concrete.

Because of the variability of natural soils, it is a difficult task to predict the performance of soil-cement blocks in practice, and a conservative approach must be adopted. Though time-consuming and severe, the A.S.T.M. durability test provides the best indication of the performance of soil-cement building under tropical conditions. Tests at low compaction energies on a wide variety o Zambian soils suggest, however, that the perdominant factor affecting durability is dry density. A correlation between these two properties may be used, with an appropriate margin of safety, to introduce great simplification into procedures or selecting soils for making soil-cement blocks.

The relevant Code of Practice gives no guide to the designer which enables him to assess the mean loads in a situation where there are unusual wind effects caused by the proximity of large buildings. The results presented here are those of a project undertaken to investigate the interference effects of a pair of square prisms on their mean lift and drag. Tests have been performed with the bodies both normal to and in-line with the flow. In addition, the wall proximity effects on the mean lift and drag on a single prism have been measured.

The dynamic response of a large building floor system, as induced by humans, has been experimentally evaluated. The human reaction to this response was related as an unsafe or unpleasant feeling. The subsequent dynamic analysis of the floor indicates that the natural frequency and induced frequency are of the same order, thus the reason for the resonance problem. The dynamic analysis, experimental study, static analysis and recommendations for eliminating the resonance problem is discussed.
