Aiming at the limitation of the calculated length coefficient of the gable portal rigid frame columns in the standards and regulations, which ignores the influence of the arch effect caused by the axial force of the inclined beams lope, this paper uses the elastic buckling equation of the solid-webbed articulated pitched-roof frame, considered second-order effect and the arch effect of the inclined beam under uniform load together. And the length coefficient calculated is analyzed. It is concluded that the larger the slope of the inclined beam and the ratio− of the rigid frame span are, the more obvious the arching effect is, and the larger the calculated length coefficient of the rigid frame column is. 1 Introduction horizontal load, there will be a second-order effect. This effect that increases the bending moment For the gable portal light rigid frame, reasonable support and displacement is called the span effect[2]. Therefore, − and tie bars can ensure the stability of the rigid frame the total lateral displacement of the column is the sum outside-plane. Therefore, the overall stability of the rigid of the lateral displacement caused by the bending frame is determined by the inside-plane stability. deformation under the vertical load and the 1 Relevant codes and regulations calculate the stability of generated by the horizontal thrust under the arch effect. the rigid frame through calculating the length coefficient. 2 Under the transverse uniform load, there is an axial force caused by the slope at the joint between the inclined beam and the vertical beam. The articulated gabled portal rigid frame exhibits arch-like characteristics in terms of stress and stability, namely the arch effect. At present, considering the stability of the gable portal frame, the related codes and regulations are to simplify the inclined beam as a horizontal beam. Such simplification fails to consider the influence of arch effect on the overall Figure 1. Span variation of pitched-roof frame stability of the rigid frame.

The swimmer hydrodynamics performance was studied by the application of computational fluid dynamics (CFD) method. The steady-state CFD simulations were performed by the application of k - omega turbulent model and volume of fluid method to obtain two-phase flow around a three- dimensional swimmer model when gliding near water surface and at different depths from the water surface. The simulations were conducted for four different swimming pool size, each with different depth, i.e., 1.0, 1.5, 2.0 and 3.0 m for three different velocities, i.e., 1.5, 2.0 and 2.5 m/s, with swimmer gliding at different depths with intervals of 0.25 m, each starting from the water surface, respectively.

  • Islamic Domes of Crossed-Arches: Origin, Geometry and Structural Behavior
    Islamic domes of crossed-arches: Origin, geometry and structural behavior P. Fuentes and S. Huerta Polytechnic University of Madrid, Spain ABSTRACT: Crossed-arch domes are one of the earliest types of ribbed vaults. In them the ribs are intertwined forming polygons. The earliest known vaults of this type are found in the Great Mosque of Córdoba in Spain built in the mid 10th century, though the type appeared later in places as far as Armenia or Persia. This has generated a debate on their possible origin; a historical outline is given and the different hypotheses are discussed. Geometry is a fundamental part and the different patterns are examined. Though geometry has been thoroughly studied in Hispanic-Muslim decoration, the geometry of domes has very rarely been considered. The geometrical patterns in plan will be examined and afterwards, the geometric problems of passing from the plan to the three-dimensional space will be considered. Finally, a discussion about the possible structural behaviour of these domes is sketched. Crossed-arch domes are a singular type of ribbed vaults. Their characteristic feature is that the ribs that form the vault are intertwined, forming polygons or stars, leaving an empty space in the centre. The fact that the earliest known vaults of this type are found in the Great Mosque of Córdoba, built in the mid 10th century, has generated a debate on their possible origin. The thesis that appears to have most support is that of the eastern origin. This article describes the different hypothesis, to then proceed with a discussion of the geometry.

  • An Alternative Explanation of the Royal and Select Master Degrees
    An Alternative Explanation of the Royal and Select Master Degrees by Sir Knight Gene Fricks The legends behind the ritual of the Royal and Select Masters degrees are among those with only a vague basis in biblical antecedents. Unlike the legend of Hiram and the building of the first temple or that of Zerubabbel and the second temple, we have only a passing mention of Adoniram as the first overseer of King Solomon and a listing of Solomon's chief officers in I Kings 4:4. We do not find the secret passageway or the nine arches described in the II Kings story of the temple's construction. Recognizing that the writers of the original rituals were men steeped in classical learning, we should look elsewhere for the source of this story. I suggest that the writings of the 15th century Arab historian, Mudjir ad-Din, may have been that source. What prompted this thought was the celebration of the 3000th anniversary of Jerusalem several years ago and the renewed interest in its ruins that the commemoration sparked. Let us review some of Jerusalem's history after the Roman destruction of Herod's Temple in 70 A.D. to set some background. Titus and his son Vespasian conquered Jerusalem after a long and bloody siege. Determined to bring the recalcitrant Jews to heel, the Roman 10th Legion, left to garrison the city, were ordered to level the temple down to its foundations. What we see today in Jerusalem is the temple mount platform upon which the temple sat, all that remains of Herod's imposing construction project.

  • Chemicals Found in Pool Water Can Be Derived from a Number of Sources
    CHAPTER 4 CChemicalhemical hhazardsazards hemicals found in pool water can be derived from a number of sources: the source Cwater, deliberate additions such as disinfectants and the pool users themselves (see Figure 4.1). This chapter describes the routes of exposure to swimming pool chemi- cals, the chemicals typically found in pool water and their possible health effects. While there is clearly a need to ensure proper consideration of health and safety issues for operators and pool users in relation to the use and storage of swimming pool chemicals, this aspect is not covered in this volume. Chemicals in pool, hot tub and spa water Source water-derived: Bather-derived: Management-derived: disinfection by-products; urine; disinfectants; precursors sweat; pH correction chemicals; dirt; coagulants lotions (sunscreen, cosmetics, soap residues, etc.) Disinfection by-products: e.g. trihalomethanes; haloacetic acids; chlorate; nitrogen trichloride Figure 4.1.

  • The Influence of the Arch
    The Influence of the Arch The Influence of the Arch by ReadWorks The lasting influence of ancient Rome is apparent in many areas of our contemporary society. Sophisticated elements of law, engineering, literature, philosophy, architecture, and art can all be traced back to the Roman Empire. But perhaps one of the most lasting contributions from Roman civilization is something we see nearly every day: the Roman arch. An arch is a curved structure designed to support or strengthen a building. Arches are traditionally made of stone, brick, or concrete; some modern arches are made of steel or laminated wood. The wedge-shaped blocks that form the sides of an arch are called voussoirs, and the top center stone, called the keystone, is the last block to be inserted. During construction, the arch is supported from below before the keystone is put in. The curve of an arch may take different shapes, but it is often a rounded or pointed semicircle. Although the Romans revolutionized the arch, the structure has been around since before them. The Assyrians used arches to construct vaulted chambers or underground drains. However, these early arches were only suitable for small structures. The designs weren't sophisticated enough to support larger edifices, like palaces or government buildings. The Romans, however, improved the arch and made it strong enough for large-scale, widespread use. By developing an arch capable of supporting huge amounts of weight, they laid the groundwork for some of the most important advancements in architectural history. The arch became a vital feature of bridges, gates, sewers, and aqueducts, which in turn were integral to the modernization of cities.
