Abstract:A practical calculating model, based on the fundamental mode generalized force spectrum (FMGFS) obtained in a wind tunnel test and presented practical higher mode generalized force spectrum (HMGFS) model in along-wind direction of lattice tower, is further deduced and proposed to calculate along-wind displacement response of lattice tower. In the proposed model, the contributions of higher vibration modes can be taken into account. As for lattice tower, it is of value to popularize the proposed model and the approach that car: provide valuable reference for code.
