Deflection limits are only needed so that sufficient stiffness is provided during construction to prevent serviceability problems, with the suggested limit being 1/600. Several methods for determining the deflection of reinforced masonry beams are examined, and a method for the effective moment of ...

Checking the steel ratio, we find the limits from Table A-8.9 to be ρmin = 0.00333 (see Note 1 for negative-moment T-beams) and ρmax = 0.02130. The actual steel ratio can be found by dividing the bar area by the gross concrete area determined by width and effective depth: for the...

Here we propose a class of angle-selective metasurfaces, over which beams are reflected following different and independent phase gradients in the light of the beam direction. Such powerful feature is achieved by leveraging the local phase modulation and the non-local lattice diffraction via inverse...
The maximum variation in wavelength induced by converter 14 and, hence, the maximum angular scan of the output beam, can be established by disabling (i.e., grating) all sensor output signals except those which will set the desired end limits of the scan. For example, if there are ten ...
