The ballastless plate girder bridge, classified as a structure type that requires an emergent replacement among domestic railway bridges, generally tends to upgrade ballasted track along with continuous welded rail (CWR). axial forces of the CWR due temperature change need be distributed bridge foundations. Because most existing bridges over 50 years age do not provide any design information, s...

Artificial neural networks (ANNs) are often used recently by researchers to solve complex and nonlinear problems. Standard penetration test (SPT) cone (CPT) field tests that obtain soil parameters. There have been many previous studies examined the value obtained through SPT with CPT test, but research carried out still uses equations linear. This will conduct an estimated of on cohesive using ...

This paper evaluated the influence of Standard Penetration Test (SPT) correction factors, namely hammer energy efficiency, borehole diameter, drill rod length, and sampling method, on correlations between SPT resistance (SPT-N) undrained shear strength (Su). Comparisons were made new equations (with without corrections), which derived from soil data collected Penang Island, Malaysia. The coeffi...

The location of Pakistan is in a collision zone among the Eurasian and Indian plate boundaries. geological framework Northwest Himalaya makes Northern susceptible to frequent moderate major earthquakes. devastating earthquake October 8, 2005 caused 87,000 deaths, 2.8 million displacements financial loss 200 Billion USD equivalent 6% GDP Pakistan. Islamabad seismically active region, studies con...

This paper investigates the effect of micropile installation into saturated sandy soil by means of finite element method. The obtained results from numerical modeling are compared with the received data from the site. The validation of software has been done by simulating standard penetration test. The effect of some changes in spacing (3m, 1.6m and 0.8m) and injection pressure (1cm, 2.5cm, 5cm...

Shear wave velocity (Vs) is known as one of the fundamental material parameters which is useful in dynamic analysis. It is especially used to determine the dynamic shear modulus of the soil layers. Nowadays, several empirical equations have been presented to estimate the shear wave velocity based on the results from Standard Penetration Test (SPT) and soil type. Most of these equations result i...

An evaluation using the liquefaction potential index (LPI) was still applicable to site conditions in Central Sulawesi 2018’s earthquake with Mw 7.5. In some areas, severe occurred and destroyed many buildings. This study conducted determine depth of layer any soil that may cause damage land. is intended obtain guidance select an area for housing, especially low-budget housing. The possibility ...

We compared a newer serum specific IgE (SSIgE) test with skin prick testing (SPT) in the diagnosis of allergy in Malaysia. Ninety newly diagnosed allergic patients were enrolled for both tests. Using SPT as a clinical gold standard, the sensitivity, specificity, positive, and negative predictive values (PPV, NPV) were calculated for SSIgE for each of the common allergens tested. The highest pos...

This research discusses the use of stone columns in increasing value safety factor on soils that have potential to experience liquefaction. study aims determine sandy soil area and after Stone Column planning. The method used liquefaction is Seed et al, based interpretation SPT (Standard Penetration Test) data using column as a improvement method. Based results study, it known each point has ex...
