Forced Vibration of a Damped SDOF System
Forced vibration of a damped SDOF system requires us to determine both transient and steady-state structural responses. The transient response is o…

Bridge-Shear Design
Prestressing tendons can improve the shear capacity of concrete section. It can also help resisting the shear force with counteracting vertical force…
Bridge-Ultimate Moment Design
When a prestressed beam is subjected to bending, one extreme fiber of the section is compressed while the another is subjected to tension. Concrete…
Bridge-Stress Check
Longitudinal stress in concrete deck varies throughout its design life. It is necessary to ensure the stress in concrete does not exceed the allowabl…
Solution for Forced Vibration for Undamped SDOF System
Let’s look at an undamped SDOF system is subjected to forced vibration while having initial displacement and velocity. The solution for the dynamic r…
Bridge-Tendons Vibration
To minimize the problem associated with the vibration of tendons, it is preferable to ensure the natural frequency of tendon is nowhere close to that…
Bridge-Deflection
The deflection of bridge deck is caused by loading and prestress. Loading, including the self-weight makes the bridge deck sags, while the prestres…
Forced Vibration of an Undamped SDOF System
When subjected to external force, a dynamic system is said to be under forced vibration. Let’s look into an undamped SDOF system under this kind of v…
