Experimental Study on Precast Concrete Shear Walls with Different Hollow Slabs
To study mechanical behaviors of shear walls built with precast two-way hollow slabs, two shear walls with different details of hollow slabs were quasi-statically tested under low cyclic loading. The failure mode was analyzed, which vertical macro-cracks appeared on walls due to the details of hollow slabs. Brittle shear failure can be avoided in terms of the failure behaviors evolved from inte...
متن کاملCOMPARATIVE COSTS OF THE PRODUCTION, TRANSPORT AND ASSEMBLY STAGES OF PRESTRESSED PRECAST SLABS USING GENETIC ALGORITHMS
In the precast structures, optimization of structural elements is of great interest mainly due to a more rationalized way that elements are produced. There are several elements of precast prestressed concrete that are objects of study in optimization processes, as the prestressed joist applied in buildings slabs. This article inquires into cost minimization of continuous and simply supported sl...
متن کاملHollow Piezoelectric Cylinder under Transient Loads
In this paper, transient solution of two dimensional asymmetric thermal and mechanical stresses for a hollow cylinder made of piezoelectric material is developed. Transient temperature distribution, as function of radial and circumferential directions and time with general thermal boundary-conditions, is analytically obtained, using the method of separation of variables and<br...
متن کاملresponse of coupled-precast shear walls subjected to cyclic loads
large panel precast structures are analyzed based on the connection rigidity. however, the connections undergo nonlinear and inelastic response, when subjected to seismic loads. thus, to study the actual behavior of structure, the connection nonlinearity should be implemented in the joints. in this paper, three conventional connection types are modeled based on the envelope of their cyclic resp...
متن کاملShear Strengthening Using Frp Sheets for a Idghw a Y Bridge in Manitoba, Canada
The use of heavier trucks demanded upgrading of a twenty-seven year old bridge in Winnipeg, Manitoba, Canada. Analysis of the precast prestressed concrete girders using the current AASHTO Code indicates a deficiency in the shear capacity. Shear strengthening using Carbon Fibre R_einforced Polymer (CFRP) sheets provides a low-cost solution by increasing the speed of construction and reducing tra...
