For conventional glass panels under heat-treatment for strength improvement, structurally they can be classified into 3 groups as annealed, heat-strengthened and tempered glass. The need for structural reinforcement usually occurs in cases where the load-bearing structures no longer meet the requirements for normal use as a result of higher loads or the appearance of unacceptable defects. The structural relaxation is shown to be approximately exponential and linear (in the relaxation nomenclature), and the relaxation time nearly follows an Arrhenius temperature dependence over some 15 decades.
