In this paper, the capabilities of passive control of structures using hydraulic fluid dampers are compared to those of semi‐active control. It is demonstrated that, in most cases, the performance achieved by a properly designed passive control system can be comparable to that of semi‐active systems that use the state‐of‐the‐art control algorithms. It is also shown that the optimum damping coefficients for passive control may be much smaller than the maximum values considered in semi‐active control. These conclusions are supported by numerical simulations of several structures, including a case of actual implementation of semi‐active control in a building structure.
