Abstract
Medellin City has a population of about 2,000,000 people and its area is lower than 110 km2. This city is located in the northwest of Colombia, that is in the northwest corner of South America, which is a zone with a complex tectonic environment associated to the interaction of the Naza, Suramerica and Caribe plates. The result of these conditions implies that Medellin has an intermediate seismic hazard. This city was developed on tie valley of Medellin River and his slopes, has a complex geology, which is composed by alluviums, colluviums of different ages, residual soils from igneous and metamorphic rocks. The Medellin Seismic Microzonation project carried out a detailed geotechnical exploration and laboratory tests to measure the dynamic properties of the different soils of the city. This paper shows the results of this studies focused to evaluate the dynamic properties of Medellin soils and determine the influence of geological origin, weathered level and index properties in its dynamic behavior. Special emphasis is given to the shear wave velocity, and to the variation of shear modulus and damping ratio with cyclic shear strain amplitude.
