| The Stability analysis of the lusi mud volcano embankment dams using FEM with a special reference to the dam point P10.Dr | Since the eruption of the Lusi Mud volcano in Sidoarjo, East Java, on May 2006, soil embankment dams have been built to keep hot mud within the ponds. Unfortunately, since the dams were sitting on poor weak ground, land subsidence intensively occurred around the dams. A finite element method (FEM) was, then, applied to ...

| Increase on strengths of hot weather concrete by self-curing of wet porous aggregate | The compressive and tensile strengths of concrete made in hot weather condition decreased due to loss of mixing water caused by high evaporation. One method to overcome the problem is the use of saturated fly ash aggregate. The water content in fly ash aggregate can flow out to the hardened cement ...

| Influence of curing age and mix composition on compressive strength of volcanic ash blended cement laterized concrete | This study investigates the influence of curing age and mix proportions on the compressive strength of volcanic ash (VA) blended cement laterized concrete. A total of 288 cubes of 100mm dimensions were cast and cured in water for 3, 7, 28, 56, 90 and 120 days of hydration with cement replacement ...

| The Effectiveness of emergency response system?s service providers for road accidents in Johor Bahru, Malaysia | In Malaysia, there are three core services involved in emergency, namely the fire and rescue, police, and ambulance services. The aim of the service providers is to prevent the loss of life and damage by improving their response time. The Civil Defence Department and the 999 call centre also assist the ...

| Settlement control of soft ground using cement-ricehusk stabilization | Cement is widely used for improvement of soft soils, but financial and environmental concerns are causing genuine concerns to all parties, leading to the quest for alternative and effective stabilizers. Ricehusk is an agricultural waste in Malaysia, commonly disposed of by open burning or dumping in landfills. Considering that the ashes ...

| Soil liquefaction in Padang due to Padang earthquake 30 September 2009 | The Padang earthquake of M7.6 on 30 September 2009 (30S?09) caused damage to buildings, houses, public water facilities, and road ways. Several buildings were damaged due to liquefaction. This paper describes the liquefaction potential in Padang based on the site observation and analytical examination. The liquefaction was observed at a number ...

| The Impact of changing storage area on flood magnitude and occurrence | This study focuses on the impact of combined catchment and storage upon flood occurrences and flood peaks. A significant factor that plays an important role of the combined catchment and storage is the ratio of contributing catchment area to storage area (AC/AS) where the impact significantly shows increasing frequency of storage ...

| Mechanical properties of clayey sand treated with cement-rubbershreds | Residual soils of clayey sand composition can potentially be treated to construct a 2-layer pavement system. Using cement as the primary binder and recycled rubbershreds (<2 mm thick, 0.425 mm - 12 mm in length) as filler material, the improved ground can serve as a reliable road foundation, overlain with a ...

| A Finite element analysis of bearing resistance of timber loaded through a steel plate | Decrease projected length of bolts due to bending deformation in timber joints compresses the steel washers onto timber member and increases lateral resistance of the joints. As this lateral strength increase primarily depend on bearing characteristics of timber beneath the steel washers, a finite element analysis was performed to predict their ...

| Technical note: an assessment of practicing reflection in teaching the concepts for engineering statics | This paper shares the experience of Dr Ande in practicing reflection in teaching the concepts for Engineering Statics. His constant pursuit of being a reflective practitioner has made him more evolved as an effective teacher and made him more flexible in modifying his practice. It is interesting to learn from Dr. ...

| Model development of rainwater management for agriculture decision support system in semi arid area | Land cultivation for agricultural purposes in semiarid area is usually carried out only once a year specifically during the rainy season. The condition is even worse since it is not without the risk of failure because of dry-spell or water-logging. To cope with this situation, the researchers developed a model of ...

| Applying fuzzy analytic hierarchy process (FAHP) ?-cut based and TOPSIS methods to determine Bali provincial road handling priority | The Analytic Hierarchy Process (AHP) method has been employed in a previous study to determine Bali provincial road handling priority. This method usually overlooks the decision maker?s degrees of confidence and optimism of the decision. Meanwhile, Fuzzy Analytic Hierarchy Process (FAHP) ?-cut based and Technique for Order Preference by Similarity to ...

| Consideration of road management from the view points of long-and short-distance road user?s satisfaction | This study observed long- and short-distance road user satisfaction with national road infrastructure in order to direct future road management strategies. The research was a quantitative research method using questionnaire translated into the Japanese Language. The questionnaires were distributed to 2000 road users of two national roads in Saga, Japan. A ...

| Effect of specimen size on the tensile strength behavior of the plastic waste fiber reinforced soil ? lime ? rice husk ash mixtures | Improvement of tensile strength in fiber reinforced soil is an important research topic. A study has been undertaken to investigate the strength of stabilized clay-soil reinforced with randomly distributed discrete plastic waste fibers by carrying out split tensile strength test. In this study, the clay soil was stabilized with lime and ...

| The Influence of rock properties and size into strength criteria: a proposed criterion for soft rock masses | A new modified strength criterion for soft rock masses is proposed in this paper in order to provide a suitable estimation for soft rock mass strength. The new criterion is based upon the current compression test data of soft materials of over 150 samples, and available published data of soft rock strength. It is ...

| Application of buckling restrained braces for seismic strengthening of irregular gravity load designed reinforced concrete frame buildings | Past earthquake disasters have shown that irregular gravity load designed (GLD) reinforced concrete (RC) frame buildings were very vulnerable to strong ground shaking. Many of them collapsed and caused loss of human lives as well as materials. Hence, in order to prevent future disasters, this type of buildings needs to be ...

| Beam to column timber joints with pretensioned bolts | The effects of pretension in bolts on hysteretic response of timber joints exposed to a bending had been reported by the authors, but the cyclic tests were carried out at small displacement level which might not be applicable for earthquake-resistance design. In this study, similar cyclic tests but at large displacement ...
