SOIL STABILIZATION BY USING CEMENT ISLAM, MD. MAHFUJUL; ALAM, MUNTASIR; FERDOUS, MD. SHAMIM; RAHMAN, M.M. MAHBUBUR Soil stabilization of soil is done by mixing Portland cement with water and compacting the mix to attain a strong material. The material obtained by mixing soil and cement is known as soil-cement. The soil cement becomes a hard and durable structural material as the cement hydrates and develops strength. Cement stabilization is done while the compaction process is continuing. During the compaction process we use some amount of cement. Some void space can be found in soil particle. Cement is just like paw, so cement can fill the void space of soil easily. As a result, void ratio of soil may reduce. After this primary tasks, when we add water in the compaction the cement reacts with water and become hard. So unit weight of soil is also may increased .Soil-cement is sometimes called cement-stabilized base, or cement-treated aggregate base. We used standard proctor test for laboratory experiment, in the laboratory experiment, we added .8%, 10%, 12%, 14%, water in the soil. From the observed data we found that for a certain limit with the of water content the value of dry density in increased, after attaining a peak point the value of dry density in decreased when we increase the amount of moisture content. From the peak value of the graph we determined maximum dry density and optimum moisture content. We continued the same experiment for different percentage of cement mixing with soil. From the experimental value we observed that maximum dry density of the sample in increase with increasing percentage of cement with sample.

A STUDY ON TRAFFIC CONGESTION DUE TO ILLEGAL PARKING IN THE ROUTE OF KAKRAIL- MALIBAGH- MOUCHAK- MOGHBAZAR ROAD RAYHAN, Md. ABU; DEY, NIKETAN; ALAM, JUNAID; NABI, IMTIAZ All mega cities of the world are characterized by huge population, congested road with heavy traffic etc. Dhaka the capital city of Bangladesh, being one of them also possesses all these characteristics. The road network of Dhaka city has been developed without any transportation planning. The city is severally affected by uncontrolled and unauthorized parking of vehicles. Haphazard parking of vehicles not only reduced the capacity of road it also reduced the productivity of network. Proper parking policy is the key to the traffic problems of an urban area. In the parking policy for the Dhaka Metropolitan Development Plan Area regulation are not very transparent and users are ignorant of such regulations. First multistoried parking in Dhaka is started at 24 Motijheel. But the facility failed to attract parker Poor conditions of on-street August 2006 at parking present in different area of Dhaka are also noticeable and from field survey the conditions are shown by the photographs. On-street parking should be strictly regulated. Regulations must be transparent and widely publicized. Users Should be made aware of the penalties that would be imposed in case of violations. High on-street parking charge should impose to discourage unnecessary trip and on-street parking policy available but it has never been implemented. The policy needs to be reviewed and revised and put into practice.

A COMPARATIVE STUDY ON MASS TRANSIT SYSTEM (BUS) IN DHAKA CITY Kamal, Mohasin; Rahman, Saidur; Hasan, Raijul; Hossain, Alamgir The specific objectives are to investigate the facilities & service qualities provided by some selected bus service. We conducted questions answer survey by passengers, drivers and helpers at various point of our selected routes and selected bus service. The study was mainly aimed at identifying the transport facilities in Dhaka city. Through there are fixed stoppages for every particular bus this is hardly maintained due to pick people from any paths resulting in increasing delay time during one trip. In peak hour maximum buses provide local services. As a result it fails to meet the mobility .The seat capacity of private buses is better than public buses. According to people opinion private transports provide more facilities although fare rate is higher. From survey it is observed that, private car reduction, ticketing system, improving traffic system and management, increasing Bypass road, and modification of the transport planning system can be helpful to increase the use of buses. Weak public mass transport, ineffective traffic control, the mix of motorized and non –motorized vehicles, poor road condition, illegal parking and the presence of hawkers contribute to excess traffic congestion and ineffective use of buses. The passengers also had given some suggestions about improvement of bus service. These are Improve maintenance system, Increase seat capacity of buses, Arrange sitting service and ticketing system.

Response of High-rise Structures under Static and Dynamic Loadings SARDAR, SHIHABUDDIN This study was carried out in the Department of Civil Engineering of Stamford University Bangladesh with the objectives of the response of high-rise structures under static and dynamic loadings and the application of static and dynamic analysis of the structures. High-rise buildings are exposed to both static and dynamic loads. Depending on the method used and how the structure is modelled in finite element software, the results can vary. Nowadays the world is going forward by the implementation of performance-based engineering analysis. Most of the multi-storied buildings in our country are still analyzed and designed without proper seismic consideration in the conventional way. Under strong earthquake, structures behaved unsatisfactory during major ground motions with large inelastic deformations, and dynamic analysis should be performed for the structure. Dynamic effects such as resonance frequencies and accelerations are considered. The variation in static results from reaction forces, overturning moments, deflections, critical buckling loads, forces between prefabricated elements and force distributions between concrete cores are investigated with different models. The structural dynamics is the direct application in design of high-rise building and structural analysis against earthquake and wind loading. Structural design for dynamic loading is primarily concerned with forces and their effects on motion. All design against seismic loads must consider the dynamic nature of the load. However, for simple regular structures, analysis by equivalent linear static methods is often sufficient. This is permitted in most codes of practice for regular, low to medium-rise buildings. Equivalent static analysis can therefore work well for low to medium-rise buildings without significant coupled lateral-torsional modes, in which only the first mode in each direction is considered. Tall buildings (say, over 75 m or 25 storied), where second and higher modes can be important, or buildings with torsional effects, are much less suitable for the method, and require dynamic analysis of the buildings.
