摘要: Abstract This paper summarizes a study undertaken to analyse the fatigue behaviour and variation on modulus of elasticity basalt fiber reinforced polymer (hereinafter-BFRP) under experimental cyclic loading. The impact load frequency amplitude ultimate strength BFRP number cycles degradation were investigated, respectively. Based results relationship stress range bars is proposed. Also, brand new non-common resistance experiments concrete beams prestressed by are introduced. Moreover, deflection crack width estimated. effect degree prestressing described main figures relationships appear in text below.
