In addition to that, you can create a movie of your staircase design in 3D in MOV format. Geometry of staircase Riser of each step Rise

Solved Example A cantilever slab mm thick is 1. We can however also design invisible supports for steps. The small notional horizontal load can generally be covered by wind What is the difference between Airport, Aerodrome and Airfield? A discussion of the factors that affect the behavior of the staircase is presented together with an abbreviated design example which illustrates only those calculations which are peculiar to this type of design. See the ideas below.

Design and Structural Dynamic Characteristics of an Irregular Staircase Under Earthquake Loading

Reinforced concrete staircases are structurally designed as cantilevered, slab type or beam-slab type. Within this study an irregular cantilevered staircase is studied and its structural dynamic characteristics are explored. An eigen-value modal analysis is performed to determine the mode shapes, their corresponding modal participation factors and natural periods of vibration. The highest modes of interest are identified. Following on that, a scaled record of a previous historical earthquake was applied within a direct integration time-history analysis in order to assess the performance of that irregular stair case under earthquake loading. That load was applied within two perpendicular load cases representing the different possible directions of earthquake vibrations in which the effect of the structure irregularity was assessed per direction. The structure was found to have large drifts creating a need to change the structural system.

In the analysis of a free-standing staircase with slab elements, approximate analytical methods are sometimes used because of the absence of specific code provisions due to their inherent limitations. These approaches, however, cannot predict the actual three-dimensional 3D behavior of the stair slab system. In addition, analytical methods cannot predict the stress resultant distribution in any section. These drawbacks highlight the need for the development of more rational but simple analysis methods for design purposes. Thus, in this study, an extensive numerical study on the behavior of free-standing staircases was performed using the finite element package SAP A sensitivity study on the different geometric parameters and material properties that affect the design force and moments was also conducted.

Emoticon Emoticon. Engineering Books. Very useful and rare books in all fields of Engineering. Preference :. Staircases is divided into five chapters: Specifications and basic data on staircases; Structural analysis of staircases — Classical methods; Structural analysis of staircases — Modern methods; Staircases and their analysis — A comparative study; Design analysis and structural detailing. Charts and graphs are included and numerous design examples are given of freestanding and other geometric staircases and of their elements and components. These examples are related to the case studies which were based on staircases that have already been constructed.

It follows the limit state design philosophy. Like the beam and slab elements, the staircase is design to check the ultimate limit and the serviceability limit states. Staircase is one such important component in a RCC structure. The riser The design of staircase, therefore, is the application of the designs of the different elements of the staircase.

 - НБ - это, конечно, не болтай. Вот такое агентство. На другой стороне авениды Изабеллы он сразу же увидел клинику с изображенным на крыше обычным красным крестом на белом поле.

 Танкадо. Сьюзан едва заметно кивнула: - Он требовал, чтобы мы сделали признание… о ТРАНСТЕКСТЕ… это стоило ему… - Признание? - растерянно прервал ее Бринкерхофф.  - Танкадо требует, чтобы мы признали существование ТРАНСТЕКСТА.

 Пожалуйста, уделите мне одну минуту.

 - Мы опустим каждый второй кадр вместе со звуковым сопровождением и постараемся держаться как можно ближе к реальному времени. На подиуме все замолчали, не отрывая глаз от экрана. Джабба нажал на клавиатуре несколько клавиш, и картинка на экране изменилась. В левом верхнем углу появилось послание Танкадо: ТЕПЕРЬ ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА Правая часть экрана отображала внутренний вид мини-автобуса и сгрудившихся вокруг камеры Беккера и двух агентов. В центре возник нечеткий из-за атмосферных помех кадр, который затем превратился в черно-белую картинку парка. - Трансляция началась, - объявил агент Смит. Это было похоже на старое кино.

Какой идиот станет делать на кольце надпись из произвольных букв. Фонтейн свирепым взглядом заставил его замолчать. - Вы меня слышите? - вмешался Беккер, чувствуя себя неловко.  - Вы все время говорите о произвольном наборе букв. Мне кажется, я должен вам сказать… что это не случайный набор букв. Все на подиуме воскликнули: - Что.

Но Дэвид знал, что никогда ей этого не откроет. Секрет выражения без воска был ему слишком дорог. Он уходил корнями в давние времена.
