Four commonly used methods are discussed in this paper which are proposed by Nikolaou et al.1, Nikolaou and Gazetas2, Mylonakis3, and Ahmad et al.4. These methods are based on Beam on Dynamic Winkler Formulation (BDWF). A BDWF code is developed to find kinematic pile bending moment at the interface of two-layer soil deposit. The parameters related to soil, pile, and excitation frequency are varied over wide range. The results of the BDWF are then compared with the simplified equations. The standard deviation and mean are worked out for all the four methods. It is found that the method proposed by Ahmad et al.4 gives the least standard deviation.","PeriodicalId":167225,"journal":{"name":"Journal of Engineering and Applied Sciences , University of Engineering and Technology, Peshawar","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129699075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To study the behaviour of bridge system, a prototype composite I-beam bridge superstructures consisting of reinforced concrete deck slab supported by four steel girders was selected and designed in accordance with the provisions of AASHTO LRFD Bridge Design Specifications. Mix design of model concrete was carried out to determine proportions of model concrete giving material properties as per requirements of the similitude.  i1oh reduced-scale model of the selected bridge system was constructed in the laboratory and instrumented with strain gages and strain gage-based displacement transducers. Static loads simulating I4I4SHTO Design Truck were applied to the model bridge through load cells and its response was measured with the help of a data logger. Numerical models of the bridge system were also developed in SAP2000 and their responses were compared with those obtained from the experiments. This paper covers mix design for model concrete, fabrication of loading assembly, and fabrication instrumentation, loading, and response measurement of reduced-scale bridge superstructure model.

A preliminary study was conducted to relate flows and sediment yields with land management from four sub-catchments and main catchment in Hilkot watershed. Climatic and stream flow data revealed that the bulk of the rainfall occurred during the monsoon i.e. July to September as discharge from all the streams was high. High flows occurred shortly after heavy storms because of the steep gradients and small catchment areas of the streams. High sediment concentrations were confined to critical periods of intense rains and during tillage/planting times when the soil is least protected and most disturbed. The objectives of study were to develop stage-discharge relationship to investigate sediment losses at different discharge levels at five hydro-stations representing different land uses. In the Hilkot watershed annual maximum rainfall ranged from 996 mm to 1458 mm while maximum monthly rainfall recorded was 319 mm. Resulting R2 values showed a strong relationship between stage and discharge. The relationship between stage and discharge was 99%, 97%, 79%, 89% and 95% at hydro-station 1, 2, 3, 4 and 5 respectively. There was a very good and clear relationship between sediment concentration and discharge on all hydro stations. In most of the cases per liter sediment concentration was below 10 grams. Only some events were most destructive when per liter concentration was above 12 mg/I. Hydrograph showed positive skewnes, with recessing time greater than the rising time. Flood reaches from base to peak flow within 3-5 hour and fell very rapidly in the sub-catchments, while it took more time at the outlet of the watershed. Normally base flow in the main stream is 20 to 50 litre/second.","PeriodicalId":167225,"journal":{"name":"Journal of Engineering and Applied Sciences , University of Engineering and Technology, Peshawar","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132965483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the study of the load cycle effects, the peculiarities of the meteorological conditions of the regions these lines are run need to be considered. NEPA classifies the Nation (Nigeria) into two zones: Zone A (South) and Zone B (North). The various effects on the lines due to loading given the peculiar atmospheric conditions in these zones were studied.

Ahmad","doi":"10.25211/JEAS.V21I2.486","DOIUrl":"https://doi.org/10.25211/JEAS.V21I2.486","url":null,"abstract":"Pile load tests cost generally about Rs.200,000/- and are included in almost all major bridge Projects in NWFP. Since in Pakistan very little work is done to understand the pile soil behavior keeping in view the local data base available, the confidence level of the designers is very low and as a result a lot of money goes on over-designing of pile or unnecessarily providing pile foundation. This work is directed towards understanding the pile soil interaction keeping in view the load settlement data available from pile load tests of various NWFP localities and their corresponding soil profiles. A good understanding of this behavior means a rise in the confidence level of the designer and much economy and safety. In this paper a simple numerical technique based on load transfer approach presented in the sister Paper' is used to capture the response of the soil to movement of pile relative to surrounding soil (t-z curve), as experimental technique of instrumenting the pile along the length of pile for the same purpose would have been very costly. This technique uses the available load settlement data from pile load test not instrumented along pile length during load testing and establishes an average t-z curve. This technique is applied to load settlement data of four pile load tests conducted in various localities of NWFP. Once the t-z curve is established for a particular pile-soil system, ilie curve can be used for the same site to carry out the parametric study i.e. to predict the effect of different length and/or diameter for the pile on the load settlement curve of pile. In addition, the settlement curve for other sites can be generated if the soil profile does not vary remarkably from that soil profile from which the t-z curve is developed. This investigation reveals that due to little effort devoted to the understanding of the Pile-Soil interaction on indigenous pile load tests data and soil profiles in Pakistan in general and in NWFP in particular, a very over conservative approach is followed in Pile designing.","PeriodicalId":167225,"journal":{"name":"Journal of Engineering and Applied Sciences , University of Engineering and Technology, Peshawar","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130096788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
