- Description
- This study investigates the ability of a finite element model in predicting nonlinear behavior and failure patterns of RC structural walls. Experimental results of walls with different shear-span ratios which failed in different modes are used for
verification. The walls are modelled in the finite element analysis program DIANA9.4.4.
Curved shell elements with embedded bar elements are used to simulate the reinforced concrete section of the walls to be analysed. This type of model does not require ‘plane sections to remain plane’ along a wall, and simulates the in-plane axial-flexure-shear
interaction without requiring any empirical adjustment. The model is found to capture the
monotonic and cyclic responses of the tested wall specimens with reasonable accuracy in terms of hysteresis curves and failure patterns. The failure patterns simulated by the model include shear, flexure, flexure-shear and flexure-out of plane modes depending on different parameters particularly shear-span ratio of the specimens. Moreover, the strain profile captured by the model was in good agreement with experimental measurements indicating that in addition to the overall global response predictions, local behaviour of the wall models can be predicted reasonably well.

- Low damage non-structural drywalls: Details and their performance

- Description
- Non-structural drywall partitions are the most common partitions used in buildings. They are usually bounded by a either a structural frame or by two floor slabs, which makes them prone to damage by imposed inter-storey deformations. Usually the loss of serviceability occurs at very low drift levels. As part of a research investigation into the development of low damage solutions for non-structural walls, experimental and numerical studies were carried out. This paper will present the seismic performances of existing as built drywall practice and the proposed low damage drywall solution. The developed low damage solution for drywall partitions, capable of reaching high level of drift without loss of serviceability, was developed based on the refinements of existing (as built) drywall construction practice. The experimental campaign confirmed the enhanced performance of the proposed low damage solution for non-structural drywalls, based on simple reconfiguration and detailing of the traditional solutions adopted in the current practice.
