For an element to be described as a reinforced concrete wall the length to thickness ratio should be equal to or greater than 4 clause 9 6 1 eurocode 2.
Design of reinforced concrete load bearing shear wall.
Design examples example 1.
Graphical user interface is provided for.
The design of shear walls involves providing adequate cross section and reinforcements to resist bending shear axial and twisting forces due to gravity and lateral loads.
It uses a graphical interface that enables the user to easily generate complex wall models.
Design problem a shear wall of length 4 m and thickness 300 mm is considered and subjected to the following forces with the grade of concrete fcd 25 n mm2 and strength of steel fyd 415 n mm2 table 1.
The thickness and the length of the walls are determined as per the design requirements.
A structural reinforced concrete shear wall in a 5 story building provides lateral and gravity load resistance for the applied load as shown in the figure below.
The changes are a result of the unsatisfactory performance of many shear walls in the chile earthquake of 2010 and the christchurch new zealand earthquake of 2011.
