Span Lengths and Deflections
Many designers believe that steel girders, because of their lower weight per foot, should have longer spans than concrete beams for […]
Space Frames
These represent one of the more efficient uses of structural materials. Space frames are threedimensional lattice-type structures that span in
Span Growth of Suspension Bridges
Figure 15.25 shows the growth of maximum spans by year. It is obvious that in the 60-year period from the Golden
Spatial variation of soil dynamic properties
The spatial variability of subsoil properties constitutes a major challenge in both the design and construction phases of most geo-engineering projects.
Spatial distribution of pores in concretes: the ITZ
Pores, especially the larger pores visible in backscatter SEM, are not distributed entirely uniformly within cement paste in concrete. One

Special Analyses
Space limitations preclude more than a brief listing of some of the special analyses required for various special types of reinforced
Sources of reactive silica
Silica, SiO2, is a component of many rocks; however, not all forms of silica react significantly with the pore solution
Spatial distribution of pores in concretes: local porous patches
The present writer has recently attempted to call attention to a feature observed in the microstructure of many concretes that
