The seismic assessment of bell towers of churches built during the colonial period in Mexico is studied. Two representative typologies of churches of the southwest of Mexico are considered. The results of non-linear static and the non-linear dynamic analyses are compared. The results show that it is not recommended the use of non-linear static analyses; being necessary the use of full non-linear dynamic analyses.

Prestressing Strand

A special study was made to evaluate the seismic response of the ribs of four reinforced concrete arch aircraft hangars and to assess methods of strengthening the ribs. The study was based on a series of non linear dynamic analyses of the arch ribs, with particular consideration being given to the choice of earthquake records, to the effect of P-delta actions on the arch responses and to the validity of the behaviour predicted by the computer program. The analyses indicated that the arch ribs could become unstable as a result of the P-delta effect acting in combination with reduction in the rib stiffness due to concrete cracking. However, the study also shows that the arches can be stablised very economically by using prestressing strand to provide cross bracing.
