When considering the case of asymmetric loading, distributed vertical force q = 20 kN/m acted on a half of the span and q = 10 kN/m was applied to the other one.
According to differences less than one percent, the computational method can be efficiently applied to the structural analysis of the under-deck cable-stayed bridge with the double-level cable-staying system both for symmetric and asymmetric loading.
According to possible live load models for footbridge design, the case of symmetric and asymmetric loading was considered and configurations of load q = 10 kN/m were used as shown in Fig.
The numerical values of extreme bending moments in the deck and a deformed shape of both analyzed structural schemes under symmetric and asymmetric loading are presented in Fig.
In case of asymmetric loading, the unconventional double-level cable-staying system causes less flexural response of the deck by means of lower extreme values of bending moments compared to the conventional bridge.
The specimens were tested under symmetric and asymmetric loading and strain data was recorded up to crack initiation.
It was mentioned earlier, that in real constructions most common is the asymmetric loading, which results that hysteresis loop's width [[bar.
The experiments were carried out under negative asymmetric loading cycles.
9 and Table 4, that under asymmetric loading the quasistatic damage depends on the stress level and is increased at highest loading levels ([r.
