“Nililihis nila ang usapan. Iniiba nila ang topic samantala simple lang naman ang tanong (They are veering away from the topic). They want the discussions to be technical when I only need a yes or no answer. Are quenched steel rebars safe to use in a seismic zone 4 country like the Philippines?”
In 2010, Engineer Emilio Morales presented the study “A CLEAR AND PRESENT DANGER 2 – THE USE OF QT OR TMT BARS IN SEISMIC ZONE 4” where he said that QT/TMT rebars behave quite differently under Cyclic loading or earthquake shaking and are also very much affected by heating, welding, bending, galvanizing and threading procedures employed in their use particularly in high rise buildings under Seismic Zone
