Loading condition is constant in magnitude and direction then we do static analysis and small variation wrt time is neglected to simplify the problem For example wooden block resting on a smooth surface The structural analysis focuses on the changes occurring in the behavior of a physical structure under observation when provided with a force or in case of structuresloadNow if this load is quasivery slowthe inertia forces from the basis of newtons first law of motion can be neglected and the analysis becomes staticThe static loads are very slow on the time rate graphStatic structure analysis methods    See Answer
