A calculation is performed according to appendix E with peak acceleration "Sp" and also is tried with design spectral response parameter Sa, Sa0, Sa*. In all cases the result is that impulsive accelaration is less than convective acceleration, Ai<Ac. According to equation E.22.214.171.124 impulsive shall be higher. API is not indicating in that case how to proceed, Do we have any alternative?, How we can solve it?
Metal can provide strength like no other material can and, throughout our history on Earth, humans have learned to harness metals for ever greater specialized applications, from radiation shielding on spacecraft to conductive components on circuits. Download Now
