Rice Husk Ash (RHA) is natural Pozzolan containing reactive silica and/or aluminum. When the material is mixed with lime in powdered form and in the presence of water, it will set and harden like cement. This work uses Osadebe’s optimization model to optimize the shear modulus of concrete made from RHA. The strengths predicted by the model are in good agreement with their corresponding experime...

Cold-formed steel (CFS) shear walls with concrete-filled rectangular steel tube (CFRST) columns as end studs can upgrade the performance of mid-rise CFS structures, such as the vertical bearing capacity, anti-overturning ability, shear strength, and fire resistance properties, thereby enhancing the safety of structures. A theoretical hysteretic model is established according to a previous exper...

The nonlinear static response of a vertically oriented coupled wall subjected to horizontal loading is presented in this research article. 3 storey interconnected with coupling beams modelled as solid elements finite element (FE) software named Abaqus CAE and the steel reinforcement wire element. For simulation concrete models, damaged plasticity constitutive model taken into consideration rese...

A prefabricated frame–shear wall structure is a major in an assembled building. To find method of connecting shear and columns that can both reduce the amount wet work required maintain adequate stiffness, we propose to vertical frame using rectangular concrete-filled steel tube keys (RCFSTKs). Static tests cast-in-place without with RCFSTKs were conducted compare their seismic performance. The...

Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...

The present study compared the performance of soldier pile and concrete bearing pad anchored wall facings. Using Abaqus finite element software, two case studies have been precisely represented for the facing designs and effects of the parameters of soil type, spacing of anchors and facings, surcharge and facing sizes were investigated. The analysis results indicate that the soldier pile method...
