optimal design of cantilever reinforced concrete retaining wall can lead considerable cost saving if its involvement in hill road formation and railway line formation is significant.  a study of weight reduction optimization of reinforced cantilever retaining wall subjected to a sloped backfill using differential evolution algorithm (dea) is carried out in the present research.  the retaining w...

In most cases, structural engineers assume a concrete floor to be a rigid diaphragm. Although this simplification is in most cases acceptable, it should be noted that such an assumption may be distrusted due to certain problems. Concrete structures with staggered shear walls are among those whose analysis should be conducted with special concern for the behavior of their floor diaphragms. Howev...

Abstract This study investigates the seismic performance of a composite structure comprising cold-formed steel and high-strength concrete. Four short shear walls composed concrete, namely, one specimen without diagonal bracing, with angle-steel two lattice were designed for testing their low cyclic loading. The cracking load, ultimate displacement, maximum horizontal bearing capacity, failure p...

This article presents the results of experimental research, which characterizes parameters and properties porous structure aerated concrete based on industrial waste. Structurally optimal representing physical-mechanical, thermal-technical concrete-based exterior wall structures have been identified. The test were carried out in research laboratories using block constructions with an compositio...

Multiscale modeling for cement-based materials, such as concrete, is a relatively young subject, but there are already a number of different approaches to study different aspects of these classical materials. In this paper, the parameter-passing multiscale modeling scheme is established and applied to address the multiscale modeling problem for the integrated system of cement paste, mortar, and...

The intention of this research was to study the impact of concrete floor surface roughness on a bovine claw model and to assess the deformation of the bovine claw model under load. The pressure distribution between the floor and the claw is the key method in this research. Monitoring foot-to-ground pressure distributions may provide insight into the relation between high local pressures and foo...
