Composite Walls

The use of composite materials in structural engineering is recent, and researchers need to investigate their behavior features. A new unit of multi-ribbed composite wall is introduced. A multi-ribbed composite wall is the main bearing-load member in multi-ribbed slab structures (MRSS). The bearing-load characteristics and seismic properties of the wall are different from those of other ordinary concrete members In order to study seismic behavior and durability of Multi-ribbed composite walls, experiments of 26 pieces of composite walls under cyclic loading were carried out, and then the hysteretic model of shear force–shear deformation is established. The hysteretic curves of typical composite walls are calculated. The calculated curves agree well with the experimental ones. The damage model is quantified. This study introduces a quantitative analysis means for evaluating seismic behavior aspects of damage and durability of multi-ribbed composite walls.

Simplified Mechanical Model

In order to promote building structure to be environmental friendly, light-weight and high-strength, a novel bamboo-steel composite wall is proposed. The composite wall is made up by sticking two pieces of bamboo plywood on the faces of a piece of profiled steel sheet utilizing structural glue. Taking thickness of the bamboo plywood and thickness and corrugation-height of the profiled steel sheet as variables, quasi-static tests were carried out on 5 specimens. Based on experimental phenomena and data, their earthquake resistant properties such as horizontal bearing capacity, ductility and energy dissipation and failure mechanism are analyzed. The results show that the bamboo plywood and profiled steel sheet can effectively work together, the composite walls possess wonderful seismic properties, and that changes of thickness or corrugation-height of profiled steel sheet make very sharp differences to the properties of the walls. Finally, a simplified mechanical model and calculation method for horizontal bearing capacity are proposed according to hysteresis curves within elastic range of these walls. The calculated values match well with the experimental ones.

Damage Processes

This work deals with an improvement of an anisotropic damage model in order to analyze reinforced concrete structures submitted to reversal loading. The original constitutive model is based on the fundamental hypothesis of energy equivalence between real and continuous media following the concepts of the Continuum Damage Mechanics. The concrete is assumed as an initial elastic isotropic medium presenting anisotropy, permanent strains and bimodularity induced by damage evolution. In order to take into account the bimodularity, two damage tensors governing the rigidity in tension or compression regimes are introduced. However, the original model is not capable to simulate the influence of the previous damage processes in compression regimes. In order to avoid this problem, some conditions are introduced to simulate the damage unilateral effect. It has noted that the damage model is agreement with to micromechanical theory conditions when dealing to unilateral effect in concrete material. Finally, the proposed model is applied in the analyses of reinforced concrete framed structures submitted to reversal loading. These numerical applications show the good performance of the model and its potentialities to simulate practical problems in structural engineering.

Composite Walls

According to the special forms and mechanical behavior of frame-composite walls, displacement calculation method for frame-composite walls under horizontal loads is proposed in this paper. The model of frames and composite walls in parallel is adopted for considering working together of them. Cracking of filling blocks at middle and end elastic stages is taken into account. Based on material and structure mechanics theories, the displacement calculation method of frame-composite walls is derived from that of frame structures. The calculation results of the proposed method agree well with the test results of multi-grid composite wall with edge frame columns reinforced by steel. The displacement calculation method of frame-composite walls is compatible with that of frames and that of RC shear walls. The shear deformation of the frame-composite wall contributes most to the whole deformation. And the lateral displacement curves of middle to high-rise frame-composite wall structures are characterized by flexure-shear deformation. The proposed displacement calculation method for frame-composite wall structures can be used as a reference for structural design
