The invention discloses a method for evaluating the wind resistance of an old tower. The method comprises: calculating and obtaining the tolerable wind speed of the old tower according to a standard combination of loads, a standard value of steel strength, a ground wire wind load reduction coefficient, a ground wire wind load pulsation reduction coefficient, a tower wind load pulsation reduction coefficient and an angle steel tower body type coefficient; calculating a load factor according to the tolerance wind speed of the old tower and a preset reference wind speed; searching a wind resistance level corresponding to the load factor from a preset wind resistance level table; and carrying out wind-resistant reconstruction on the old tower line according to the wind-resistant capability grade. The embodiment of the invention further provides a device and equipment for evaluating the wind resistance of the old tower and a storage medium, and the problem that in the prior art, the wind resistance of the old tower cannot be evaluated, and consequently the windproof reinforcement transformation cost is too high is solved.
