The use of concrete block paving for roads began in Holland after the second World war, it originated as a substitute for brick paving, the traditional surface material which was unavailable due to coal shortages. The substitution became hugely successful - the roads of post-war Rotterdam were almost entirely constructed from concrete block paving and today there is more paving on the city''s roads than bituminous materials. The reason is part...

Any Structure can be classified as B(Beam or Bernoulli)regions and D(disturbed/discontinuity) regions. B-regions are in which Bernoulli's hypothesis of straight-line strain profile applies. D-regions are parts of structure with a complex variation in strain profile. D-regions include portions near abrupt changes in geometry or concentrated forces. Based on St.Venant's principle, the extent of D-region spans about one section depth of the regio...
