The slenderness ratio of wall panel is 30 and its aspect ratio is 3. The specimen is constructed on strong floor and tested under lateral quasi-static reversed cyclic loading from 0.1% drift up to 3% drift. The flexural strength of monolithic wall depends on the spacing of transverse and longitudinal bars in the potential plastic zone which located one-fifth height of wall. The percentage of longitudinal and transverse reinforcement ratios in this type of wall are 0.84% and 0.25%, respectively. These percentages of reinforcement bars are exceeding the minimum percentage of 0.24% as specified in BS 8110 which provide in both directions. Experimental results show that wall panel starts to crack at 0.25% drift and fully cracks on the surface of the wall at 1.0% drift. Spalling of concrete cover at bottom corner of the wall starts at 2.0% drift and become worse at 2.5% drift. The specimen reduces the strength degradation at 2.5% and longitudinal bars fractured at 3.0% drift. Overall results showed that monolithic precast reinforced wall panel performs well up to 1.0% drift (the wall behaving in elastic region) but performed badly after 1% drift until 3 % drift (under elasto-plastic and plastic regions) where strength degradation occurs. 2011-08-26T13:48:14Z 2011-08-26T13:48:14Z 2008-09 Article The Journal of the Institution of Engineers, Malaysia, vol. 69(3), 2008, pages 10-17 0126-513X http://www.myiem.org.my/content/iem_journal_2008-179.aspx http://hdl.handle.net/123456789/13624 en The Institution of Engineers, Malaysia
