1. Analytical determination of the vibration frequencies and buckling loads of slender reinforced concrete towers
Abstract This study focused on improving the design of slender structures with reinforced concrete (RC) telecommunication towers as the main application. Analytical procedure based on Rayleigh’s method to compute the first natural vibration frequency and the critical buckling load was development. All the nonlinearities present in the system were considere

2. Uma avaliação experimental e numérica do efeito da rigidez geométrica na resposta dinâmica de estruturas esbeltas sujeitas à excitação de vento. / An experimental and numerical evaluation of the geometric stiffness effect on the dynamic response of slender structures under wind excitation.
Due to a politically and economically pragmatic decision, Brazil has chosen to intensely develop its cellular phone system, in order to bypass a stage of development. Once the decision has been taken, implementation was set in an explosive pace in the 1990s decade by installing tens of thousands of stations. As the electronic systems are usually more expensi

3. ESTRUTURAS TRELIÇADAS ESBELTAS SOB AÇÃO DO VENTO / LIGHT LATTICE STRUCTURES UNDER WIND ACTION
No projeto de estruturas treliçadas esbeltas, um ponto relativamente em aberto é quanto à resposta dinâmica dessas torres sob ação do vento. Já foram observadas várias ocorrências de queda de torres por tais efeitos no Brasil e ultimamente, essas incidências vêm aumentando, trazendo diversos transtornos e prejuízos significativos à sociedade e �

4. VIBRATION CONTROL OF SLENDER TOWERS WITH A PENDULUM ABSORBER / ABSORSOR PENDULAR PARA CONTROLE DE VIBRAÇÕES DE TORRES ESBELTAS
In the present work the performance of a pendulum absorber in the vibration control of tall and slender towers, caused by dynamic loads, such as, environmental loads, is studied in detail. Due to the possibility of large amplitude oscillations, the non-linearity of the pendulum is considered in the modeling of the problem. The main objective of this research
