Topology optimization in the time domain of structures subjected to time-dependent loads is usually computationally expensive, starting with the large number of time-dependent analyses that are required. Futhermore, the computational cost to evaluate the gradients of the response is significantly high and requires a large storage space. In this paper, instead of solving the original dynamical problem directly, we solve a sequence of static response optimization problems with many load cases. This approach, called the equivalent static loads method, generates static loads that produce a similar response in comparison to the same response that the dynamic analysis does. In order to verify the approaches present in the literature, a MATLAB code was developed, and several representatives examples are presented.
