CAN YOU PLEASE EXPLAIN WHAT IS SEISMIC -H AND SEISMIC -V???
IF I M RIGHT H FOR HORIZONTAL AND V FOR VERTICAL.
NOW MY 2ND QUESTION IS WHEN WE NEED TO CONSIDER SEISMIC- H AND WHEN WE NEED TO CONSIDER SEISMIC -V CASES????
Yes, your understanding is correct. V and H stands for vertical and horizontal.
In some seismic codes like ASCE7, we need to consider horizontal and vertical seismic in same combinations. Just to help the program to create automatic load combination for those cases, we used these terminologies.
