Coupling effect between masonry spandrels and piers

In-plane performance of masonry load-bearing walls was tested in a quasi-static fashion by loading individual brickwork perforated walls with constant normal force and increasing lateral force. Fifteen full-scale unreinforced frames were constructed by professional bricklayers, from ordinary bricks and lime-mortar according to ancient techniques, so as to be representative of historic masonry. Each wall was subjected to two monotonic loadings (with unloading), up to the full drop-off in the stiffness and complete development of the kinematic mechanism. The specimens exhibited significant overstrength with respect to the strength provided by the masses and high deformation capacity, which are not adequately represented by code provisions for analysis of ancient masonry buildings. The overstrength is here described by several key parameters, namely: (1) Level of coupling piers by spandrels, (2) virtual work done by interlocking and friction forces, (3) and maximum tensile stress in the top spandrel and nodal panels. The paper attempts also to calibrate the behavior factors (q) for masonry frames that are not overly conservative, as code-prescribed q-factors are. Thus, another key issue in the paper is to derive q-factors directly on the basis of the measured values to reproduce the overstrength, allowing for the normal force in the piers and the masonry texture of the wall.

Discrete variable optimization of frames using a strain energy criterion

This paper reports on recent advances concerning a new method for the weight (discrete variable) optimization of frames under both stress and multi-displacement constraints using a criterion based on the distribution of the virtual strain energy density. The proposed methodology is based on an idea that has been previously demonstrated and successfully applied on truss structures. The influence of each participating beam is defined through properly normalized sensitivity factors. An iterative formula, similar to that used for trusses, is proposed for updating the second moment of inertia followed by an improvement of shape variables (e.g. height, width, thickness) on the cross-section. The proposed method is successfully compared with the sequential quadratic programming method and other techniques published in the most recent literatures.

Hydroforming Process Design Using Finite Element Simulation for a Vehicle Instrument Panel Support Frame

Tubular hydroforming has attracted increased attention in the vehicle industry recently. This paper covers a complete hydroforming process design for an instrument panel frame by finite element simulation using the explicit code LS-DYNA. The manufacturing process for the instrument panel frame consists of tube pre-bending and final hydroforming. To accomplish hydroforming process design successfully, a thorough investigation of proper combination of process parameters such as internal hydraulic pressure and axial feeding is carried out by finite element simulation to predict the tube wall thickness and shape. An optimized process parameter combination is obtained and verified by the instrument panel frame hydroforming experiment. The experiment shows that designed process parameters can be used in real production through FEA simulation, but tubular thinned amplitude by FEA is less than that with the experiment.
