Yeka sub-city is located in the North East part of Addis Ababa. The geographicalrnlocation of Yeka subcity is 9rn0rnâ€™rn12rn0rn latitude N and 38rn50â€™ E longitude. The subcity is rncharacterized by variable topographic features. Addis Ababa is located in seismic zone 3rnaccording to ES EN 2015. The city has moderate seismicity. However, if damage occursrndue to moderated seismic activity, its effect might be significant compared to anrnearthquake occurring on remote areas. Yeka subcity is one of the highly populated areasrnof Addis Ababa. To reduce future seismic damages, itâ€™s necessary to determine thernresponse of soil deposits in the subcity .Hence the objective of this research is torninvestigate the dynamic properties of soils found in Yeka subcity. rn The index properties investigated in this study include; particle size analysis, atterbergrnlimits, free swell and specific gravity. The result of the study showed that, liquid limitrnranges from 53 to 85 %, plasticity index ranges between 23 to 45 %, specific gravityrnvalues are between 2.61 to 2.71 and free swell ranges 59 to 128 %. . rnAccording to Unified Soil Classification System, common soils found in Yeka subcityrnare classified as elastic silt and plastic clay. In this paper, the shear modulus and dampingrnratio values of soils commonly found in Yeka subcity was determined using cyclicrnsimple shear test machine on undisturbed samples. The tests were conducted as arnfunction of strain amplitude of 0.01 %, 0.1 %, 1 %, 2.5 % and 5 % under axial stress ofrn100 kPa, 200 kPa, and 400 kPa. rnThe normalized shear modulus values were determined and the results were comparedrnwith curves developed by (Seed and Idriss 1970; Vucetic and Dobry 1991; Dimer 2013;rnGemechu 2011; Mengistu 2014).The results reveal that the normalized shear modulusrnvalues at lower strains (< 0.01 %) are lower than published literature data. This reductionrnin values could be due to sample preparation and testing condition. However for higherrnstrains, the computed shear modulus values are within the limits indicated in publishedrnliterature data.Comparisons were also made with local soils. The shear moduli of the studied soils arernfitted well with curves developed for clay soils of Arbaminch and very close to silty soilsrnof Adama. However, the values show slight scatter with silty soils of Ziway. rnThe determined damping ratio values for confining stress of 100 and 200 kPa are withinrnthe curve provided by Seed and Idriss (1970) for saturated clays. However, for confiningrnstress of 400 kPa the values are outside the limits.
