This paper studies the effective stiffness of reinforced concrete rc squat walls under lateral loads.

Stiffness of reinforced concrete walls.

The presence of reinforcing steel dramatically increases the overall strength characteristics of masonry or concrete. A reinforced wall either poured concrete or concrete block always contains some form of reinforcing steel. In their discussion of stiffness modifiers for frame members they emphasize the inherent approximation in the use of stiffness modifiers. Reinforced concrete rc also called reinforced cement concrete or rcc is a composite material in which concrete s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.

Prediction of the seismic response and proper. Two large scale reinforced concrete walls without aci 318 14 special boundary elements were tested under constant axial gravity load of 0 053agfc combined with reversed cyclic quasi static. Paulay and priestley provide recommendations for stiffness modifiers for cracked concrete frame members and shear walls. Determination of wall stiffness is of particular importance for establishing design forces on attached equipment.

They often act as primary elements of a structure s lateral stability systems and by doing so are subjected to high in plane bending forces. Assessing the damage severity of buildings after an earthquake is an important part of the emergency inspection operation of buildings. They support vertical loads and are vulnerable to minor axis bending.

Paulay and priestley 1992 seismic design of reinforced concrete and masonry buildings. Rc squat walls have height to length ratios less than or equal to 2. For walls designed in. Strength of reinforced concrete sections amount of rebar a s the project calls for 5 10 and 5 12 are used.

Reinforced concrete walls with height to length ratios of approximately two and less are commonly used in power plant structures to resist earthquake effects. The coe cient of normal force influence can have a value of 0 cw 1 25. The basis for the effective stiffness values or expressions and their applicability to nuclear power plant elements is not clearly presented in current seismic standards. Strength reduced from 136 7 to 114 9 in kips.

The reinforcement is usually though not necessarily steel reinforcing bars and is usually embedded passively in the concrete before the.
