the effects of traffic frequency and skid trail slope on dry bulk density, litter mass and rutting are examined. treatments included a combination of four different traffic frequencies (3, 7, 14, and 20 passes of a rubber skidder) and three levels of slope ( 20%.) the results showed that dry bulk density, rut depth and soil displacement increased with the increase of traffic frequency and slope...

Code design of unreinforced masonry (URM) brick buildings is based on elastic analysis, which requires as input, among others, estimates of the in-plane drift capacity at the considered limit states. Current approaches assess the drift capacity of URM walls by means of empirical models with most codes relating the drift capacity to the failure mode and wall slenderness. Comparisons with experim...

This work evaluates the performance of a number of seismic assessment procedures when applied to a case study reinforced concrete (RC) wall building. The performance of each procedure is evaluated through its ability to accurately predict deformation demands, specifically, roof displacement, inter-storey drift ratio and wall curvatures are considered as the key engineering demand parameters. Th...

The geogrid-reinforced soil structures play important roles in the reinforcement applications since 1980s. Generally in design of the geogrid-reinforced soil structures, the soil-geogrid interaction behavior is not directly considered. Instead, the interaction strength is represented by the consolidation drained strength of soil commonly. However, neglecting the effect of compaction and suction...

Abstract The preliminary findings of cyclic tests conducted on a series half-scale unstrengthened and strengthened masonry walls are presented. Reinforced were by (i) non-prestressed near surface mounted (NSM) glass fibre reinforced polymer (GFRP) bars (ii) prestressed NSM GFRP. Walls symmetrically vertical passing through both mortar bricks. structure was subjected to concurrent sustained unif...

this paper develops an analytical method to calculate seismic bearing capacity of a strip footing, which is located on a slope reinforced with rows of pile. the resistance of passive pile is determined based on normal and shear stress of the soil around the pile, which is then compared to other analytical methods. this comparison indicates an acceptable agreement. the variants of the study incl...

The dynamic reaction of the natural type retaining wall is quite complex. Wall development and pressure rely upon soil underneath a backfill. greater part present knowledge has originated from model test numerical analysis. This paper aims to know behavior Also, under effect machine foundation, modeling used concerning method finite element. Two amplitudes foundation subjected three frequencies...

In order to study the influence of two parameters, height-thickness ratio and reinforcement ratio, on compressive performance prefabricated recycled concrete block-filled core walls, author proposes a test method for strength wall structures. this method, 9 walls dry full-fill masonry are used, measuring device arrangement points designed carry out loading test. The results showed that can sign...
