{"title":"Effect of Infill Walls on Response of Multi Storey Reinforced Concrete Structure","authors":"Ayman Abd-Elhamed, Sayed Mahmoud","volume":101,"journal":"International Journal of Environmental and Ecological Engineering","pagesStart":578,"pagesEnd":583,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/10001324","abstract":"The present research work investigates the seismic\r\nresponse of reinforced concrete (RC) frame building considering the\r\neffect of modeling masonry infill (MI) walls. The seismic behavior of\r\na residential 6-storey RC frame building, considering and ignoring\r\nthe effect of masonry, is numerically investigated using response\r\nspectrum (RS) analysis. The considered herein building is designed\r\nas a moment resisting frame (MRF) system following the Egyptian\r\ncode (EC) requirements. Two developed models in terms of bare\r\nframe and infill walls frame are used in the study. Equivalent\r\ndiagonal strut methodology is used to represent the behavior of infill\r\nwalls, whilst the well-known software package ETABS is used for\r\nimplementing all frame models and performing the analysis. The\r\nresults of the numerical simulations such as base shear,\r\ndisplacements, and internal forces for the bare frame as well as the\r\ninfill wall frame are presented in a comparative way. The results of\r\nthe study indicate that the interaction between infill walls and frames\r\nsignificantly change the responses of buildings during earthquakes\r\ncompared to the results of bare frame building model. Specifically,\r\nthe seismic analysis of RC bare frame structure leads to\r\nunderestimation of base shear and consequently damage or even\r\ncollapse of buildings may occur under strong shakings. On the other\r\nhand, considering infill walls significantly decrease the peak floor\r\ndisplacements and drifts in both X and Y-directions.","references":"[1] Flanagan, R.D., Bennett, R.M.: \u201cIn-plane Behavior of Structural Clay\r\nTile Infilled Frames\u201d Journal of Structural Engineering, Vol. 125, No.\r\n6, pp. 590-599, 1999.\r\n[2] Hao, H., Ma, G., Lu, Y.: \u201cDamage Assessment of Masonry Infilled RC\r\nFrames Subjected to Blasting Induced Ground Excitations\u201d Journal of\r\nEngineering Structures, Vol. 24, pp. 799-809, 2002.\r\n[3] Kodur, V.K.R., M.A. Erki, and J.H.P.
