Abstract
An inelastic finite element model to simulate the behaviour of 3D reinforced
concrete frames infilled with masonry panels subjected to static load and
earthquake excitation has been presented. Under the loads the mortar may crack,
causing sliding and separation at the interface between the frame and the infill.
Furthermore, the infill may become cracked and/or crushed which then changes
its structural behaviour. It may render the infill ineffective leaving the bare frame
to take the entire load, which may lead to the failure of the framing system itself.
In the present study, 3D reinforced concrete infilled frames have been analysed
using the finite element method.
Keywords: infilled frames, inelastic, dynamic response, 3D reinforced concrete.
1 Introduction
Holmes [4] and Smith [12] proposed the concept of infill as an equivalent
diagonal compression strut. Liauw and Kwan [6] examined the nonlinear
behaviour of non-integral infilled frames using the finite element method. The
nonlinearities of material, structural interface, effects of initial lack of fit and
friction at the interface were taken into account. Papia [8] used the boundary
element method to model the behaviour at the frame and the infill interface.
Haddad [3] analysed cracked frames with masonry infill using the finite element
method and fracture mechanics.
May and Naji [7] carried out nonlinear analysis of 2D infilled frames under
monotonic and cyclic loadings using the finite element method. Choubey and
