The building complex comprises a multibay melting shop and finishing mill building. The melting shop consists of a melting bay, a hopper storage bay, an intermediate bay and a casting bay. The finishing shop consists of a rolling shop bay, a finishing mill bay and a motor and power room bay. The finishing shop is located adjacent to the melting shop. The two buildings are separated by an expansion joint. The spacings of the stanchions in the melting bay, storage hopper bay, intermediate bay and casting bay are In the finishing shop, all columns are spaced at 30 m centres.

In the melting shop, the height of the building to the eaves level is In the finishing shop, the height of the building to the eaves level is Both buildings house overhead electric cranes. Overhead electric cranes, of capacities ranging from t kN to 80 t kN , run through the melting, intermediate and casting bays. The finishing shop carries cranes of capacities ranging from 80 t kN to 40 tons kN. The storage hopper bay consists of hoppers storing heavy briquette iron, coke and limestone to supply to the melting furnace during operation.

The top level of the gantry crane girders in the finishing shop is 14 m from the operating floor level, and in the melting shop the top of the gantry crane girders is 25 m from ground level in the melting and intermediate bays and 24 m from ground level in the casting bay. The crane girders in the melting and intermediate bays are of built-up welded-plate girder construction, and in the rest of the bays normal universal beams are used.

The stanchions and roofs are of fabricated trussed-type construction and shop fabricated. Horizontal and vertical bracing systems are provided along the horizontal and vertical planes of the roof trusses and stanchions to resist wind and crane surges, respectively.

Before we proceed with the actual analysis and design of the structure, we need to consider the following aspects in order to reach a satisfactory solution to the problem:. This building plays a vital role in the production of finished steel products.

The melting and finishing shop, built adjacent to each other, form an important heavy industrial building complex with heavy cranes running throughout the building when it is operational.

Within the building, a conveyor system supplies materials such as heavy briquette iron, coke and limestone. These materials are stored temporarily in bins hanging in the storage hopper bay. During operation, these raw materials are fed into the furnace through a conveyor system. The molten metal is then transferred to the casting bay by cranes. From here the product is transported to the finishing bay to be used in the production of continuous plate, which is rolled in the roller bay.

The final product is transferred to the storage building. The whole operation is automatically controlled from a control room adjacent to the finishing bay. Power is supplied from a generator situated in the motor and power house bay. The choice of the structural arrangement between alternative possible arrangements and the choice of the spacing of the frames are dependent mainly on the mechanical layout of the machines and equipment.

They are also dependent on finding the most economical methods for mechanical handling, operations and the movement of raw materials and final products. The storage and transfer of materials are generally unidirectional.

As a result, the frames of the building structure should be oriented at right angles to the direction of movement of the conveyor system and cranes, enabling the storage and transportation of the raw materials fed into the furnace, and transfer of the final shop products to storage. Structural system and type Structural systems may be classified as follows: — simple system of construction; — semi-continuous semi-rigid construction; — continuous rigid construction. In the simple system of construction, the members behave as hinge connections at joints so as not to develop any moment at the joint or to transfer moments to the adjacent members.

The structure should be braced in both directions to provide stability against sway. This type of system is easy to analyse and is generally used in simple types of construction where the structural arrangement is not restricted from the point of view of availability of space and architectural appearance, and also is not subjected to complicated loadings.

In the semi-continuous or semi-rigid system, the joints are assumed to have some strength and stiffness so that they can transfer moments between members. In practice, it is difficult to quantify the moment transfer between the members. This system is used in special circumstances when we are able to correctly quantify the stiffness of the joints.

In the continuous rigid system of construction, the joints between members are considered to have full rotational stiffness and rigidity so that they can transfer moments and forces between members, and to be capable of resisting moments and forces. This type of construction is represented by portal frame structures.

The frames are designed and fabricated with particular attention to the joints between the members. In industrial buildings, rigid portal frame structures are frequently used where space restrictions are the main consideration. In our case, frames consisting of stanchions and roof trusses are arranged at certain spacings along the length of the building to suit the machine and equipment layout.

The heavy overhead electric cranes, supported on gantry girders, travel along the length of the bays to feed the furnaces and machines and for maintenance of the furnaces and machines. The stanchion and truss connections are assumed to be hinged at the top of the stanchions, and the bases of the stanchions are assumed to be fixed.

The structural layout and design of the building must be chosen based on the buildability of the structure from the point of view of fabrication, erection, maintenance and services with minimum interference with existing adjacent structures and with regard to the operation of the equipment inside the building. This item depends on environmental requirements and susceptibility to weather.

In many industrial projects, the machines and equipment do not need any enclosure to guard against weather conditions during operation or maintenance. In our case, however, the building complex houses heavy machines and equipment for the melting and finishing of steel products. Therefore, the building needs roof and side enclosures during operation and maintenance to guard against all weather conditions.

In general, two main types of construction material are in use in most industrial and service sector projects, namely steel and concrete. The selection of either steel or concrete as a building material depends on the following factors:. The structural complex under consideration is to be built in a developing country. The procurement of steel within the timeframe of a project is sometimes difficult; however, ensuring that the appropriate construction material is used is paramount when the functions of the building are considered.

Moreover, selecting a material that supports speedy construction avoids delays to the project, which consequently impacts on production and operational costs; the construction of the building lies on the critical path and is considered to be in the sequence of the operational process.

Also, the structure carries very heavy overhead cranes with appreciable degrees of mechanical vibration during operation, thus generating some fatigue stress in the material.

Considering the above points, we conclude that we should choose steel as the construction material for the above building. Your email address will not be published. Table of Contents.

Разве это не услуга. Сьюзан промолчала. Она поняла: все дело в деньгах. Она перенеслась мыслями в тот вечер, когда президент Джорджтаунского университета предложил Дэвиду повышение - должность декана факультета лингвистики. Президент объяснил, что преподавательских часов будет меньше, бумажной работы больше, - но гораздо выше будет и жалованье. Сьюзан хотелось закричать: Дэвид, не соглашайся. Это не принесет тебе радости.

Панк брезгливо ее пожал. - Проваливал бы ты, пидор. Беккер убрал руку. Парень хмыкнул. - Я тебе помогу, если заплатишь. - Сколько? - быстро спросил Беккер.

 Предпочитаю вид спорта, в котором я могу выиграть. - Победа любой ценой? - улыбнулась Сьюзан. Защитник Джорджтауна перехватил опасную передачу, и по трибунам пронесся одобрительный гул. Сьюзан наклонилась к Дэвиду и шепнула ему на ухо: - Доктор. Он смотрел на нее с недоумением. - Доктор, - повторила .



 Ты должен это сделать! - потребовала она и, отвернувшись, начала что-то печатать на клавиатуре Большого Брата.  - Мне нужен список очередности работы на ТРАНСТЕКСТЕ. Если Стратмор обошел фильтры вручную, данный факт будет отражен в распечатке. - Какое отношение это имеет к директорскому кабинету. Мидж повернулась на вращающемся стуле. - Такой список выдает только принтер Фонтейна.

Техника извлечения.

Ему захотелось увидеть ее глаза, он надеялся найти в них избавление. Но в них была только смерть. Смерть ее веры в. Любовь и честь были забыты. Мечта, которой он жил все эти годы, умерла.

ГЛАВА 127 Собравшиеся на подиуме тотчас замолчали, словно наблюдая за солнечным затмением или извержением вулкана - событиями, над которыми у них не было ни малейшей власти. Время, казалось, замедлило свой бег. - Мы терпим бедствие! - крикнул техник.  - Все линии устремились к центру. С левого экрана в камеру неотрывно смотрели Дэвид и агенты Смит и Колиандер.

 - Стратмора, похоже, удивило ее недоумение.  - Мне пришлось его проинструктировать. - Проинструктировать.

Компьютер однократно пискнул. На экране высветилось: СЛЕДОПЫТ ОТПРАВЛЕН Теперь надо ждать. Сьюзан вздохнула.

 Выбросьте пробелы и наберите ключ! - не сдержался Бринкерхофф. Фонтейн повернулся к Сьюзан. - Как вы думаете, мисс Флетчер. Сьюзан задумалась. Она чувствовала, что здесь что-то не то, но не могла сообразить, что .
