The document provides information about space frames. It discusses that a space frame is a truss-like, lightweight rigid structure constructed from interlocking struts in a geometric pattern. Space frames can span large areas with few interior supports because they are strong due to the inherent rigidity of triangles and how loads are distributed as tension and compression along struts. The document outlines different types of space frame configurations based on curvature and number of grid layers, and discusses their properties, design, construction, and historical development.

In architecture and structural engineering, a space frame or space structure is a truss-like, lightweight rigid structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut.

This presentation is an attempt of a comprehensive study about Gridshell Structures.To understand the structure and it's principles we are going to take a look at it's definition. advantages, form development,materials, construction process and joint connections
In order to gain a better understanding of the structure, existing Gridshells have been analysed and studied in depth. Structures Analysed are The Savill Building, Mannheim Multihalle and Centre Pompidou Metz.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

4. •SPACE FRAMES WERE INDEPENDENTLY DEVELOPED BY ALEXANDER GRAHAM BELL AROUND
1900 .
•BELL'S INTEREST WAS PRIMARILY IN USING THEM TO MAKE RIGID FRAMES FOR NAUTICAL AND
AERONAUTICAL ENGINEERING, WITH THE TETRAHEDRAL TRUSS BEING ONE OF HIS INVENTIONS,
HOWEVER FEW OF HIS DESIGNS WERE REALIZED.

•IN THE PAST FEW DECADES, THE SPREAD OF SPACE FRAME WAS MAINLY DUE TO ITS GREAT
STRUCTURAL POTENTIALAND VISUAL BEAUTY . NEW AND IMAGINATIVE APPLICATIONS OF SPACE
FRAMES ARE BEING DEMONSTRATED IN THE TOTAL RANGE OF BUILDING TYPES,LIKE:
•SPORTS ARENAS
•EXHIBITION PAVILIONS
•ASSEMBLY HALLS
•TRANSPORTATION TERMINALS
•AIRPLANE HANGARS
•WORKSHOPS, AND WAREHOUSES ENCLOSURES
6. •MANY INTERESTING PROJECTS HAVE BEEN DESIGNED AND CONSTRUCTEDALL OVER THE
WORLD USING A VARIETY OF CONFIGURATIONS
7. •LIGHTWEIGHT -THIS IS MAINLY DUE TO THE FACT THAT MATERIAL IS DISTRIBUTED
SPATIALLY IN SUCH A WAY THAT THE LOAD TRANSFER MECHANISM IS PRIMARILY AXIAL;
TENSION OR COMPRESSION. CONSEQUENTLY, ALL MATERIAL IN ANY GIVEN ELEMENT IS
UTILIZED TO ITS FULL EXTENT. FURTHERMORE, MOST SPACE FRAMES ARE NOW CONSTRUCTED
WITH ALUMINUM, WHICH DECREASES CONSIDERABLY THEIR SELF-WEIGHT.
• MASS PRODUCTIVITY-SPACE FRAMES CAN BE BUILT FROM SIMPLE
PREFABRICATED UNITS,WHICH ARE OFTEN OF STANDARD SIZE AND SHAPE. SUCH UNITS CAN
BE EASILY TRANSPORTED AND RAPIDLY ASSEMBLED ON SITE BY SEMI-SKILLED
LABOR.CONSEQUENTLY,SPACE FRAMES CAN BE BUILT AT A LOWER COST.
•STIFFNESS-A SPACE FRAME IS USUALLY SUFFICIENTLY STIFF IN SPITE OF ITS LIGHTNESS. THIS IS
DUE TO ITS THREE- DIMENSIONAL CHARACTER AND TO THE FULL PARTICIPATION OF ITS
CONSTITUENT ELEMENTS.
•VERSATILITY -SPACE FRAMES POSSESS A VERSATILITY OF SHAPE AND FORM AND CAN
UTILIZE A STANDARD MODULE TO GENERATE VARIOUS FLAT SPACE GRIDS,LATTICED
SHELL, OR EVEN FREE-FORM SHAPES. ARCHITECTS APPRECIATE THE VISUAL BEAUTY AND
THE IMPRESSIVE SIMPLICITY OF LINES IN SPACE FRAMES

RIGIDITY OF THE TRIANGLE AND COMPOSED OF LINEAR ELEMENTS SUBJECT ONLY TO AXIAL TENSION

EACH MEMBER IS ACTED UPON BY TWO EQUAL

THE FORCES ARE ACTING ALONG THE AXIS OF

ONE OR MORE THEN ONE MEMBER OF FRAME IS
SUBJECTED TO MORE THEN TWO

AT LEAST ONE MEMBER IS SUBJECTED TO

•THE MERO CONNECTOR WAS ORIGINALLY DEVELOPED FOR DOUBLE-LAYER GRIDS. DUE TO THE
INCREASING USE OF NON-PLANAR ROOF FORMS, IT IS REQUIRED TO CONSTRUCT THE LOAD-BEARING
SPACE FRAME INTEGRATED WITH THE CLADDING ELEMENT.
•ANEW TYPEOF JOINTING SYSTEM CALLEDMEROPLUSSYSTEMWAS DEVELOPED SO THAT A VARIETY
OF CURVED AND FOLDED STRUCTURES ARE POSSIBLE.
21. •THE METHOD CHOSEN FOR ERECTION OF A SPACE FRAME DEPENDS ON:
• ITS BEHAVIOR OF LOAD TRANSMISSION
•CONSTRUCTIONAL DETAILS, SO THAT IT WILL MEET THE OVER ALL REQUIREMENTS OF QUALITY,
SAFETY,SPEED OF CONSTRUCTION,AND ECONOMY
•THE SCALE OF THE STRUCTURE BEING BUILT,THE METHOD OF JOINTING THE INDIVIDUAL ELEMENTS,
AND THE STRENGTH AND RIGIDITY OF THE SPACE FRAME UNTIL ITS
FORMISCLOSEDMUSTALLBECONSIDERED.
22. •INDIVIDUAL ELEMENTS ARE ASSEMBLED IN PLACE AT ACTUAL ELEVATIONS, MEMBERS AND
JOINTS OR PREFABRICATED SUBASSEMBLY ELEMENTS ARE ASSEMBLED DIRECTLY ON THEIR
FINAL POSITION.
•FULL SCAFFOLDINGS ARE USUALLY REQUIRED FOR THIS TYPEOF ERECTION. SOMETIMES ONLY
PARTIAL SCAFFOLDINGS ARE USED IF CANTILEVER ERECTION OF SPACE FRAME
CANBEEXECUTED. THE ELEMENTS ARE FABRICATED AT THE SHOP AND TRANSPORTED TO THE
CONSTRUCTION SITE,AND NO HEAVY LIFTING EQUIPMENT IS REQUIRED.
23. •THE SPACE FRAME IS DIVIDED ON ITS PLAN INTO INDIVIDUAL STRIPS OR BLOCKS. THESE UNITS
ARE FABRICATED ON THE GROUND LEVEL, THEN HOISTED UP INTO ITS FINAL POSITION AND
ASSEMBLED ON THE TEMPORARY SUPPORTS.
•WITH MORE WORK BEING DONE ON THE GROUND, THE AMOUNT OF ASSEMBLING WORKATHIGH
ELEVATION IS REDUCED. THIS METHOD IS SUITABLE FOR THOSE DOUBLE LAYER GRIDS WHERE THE
STIFFNESS AND LOAD-RESISTING BEHAVIOR WILL NOT CHANGE CONSIDERABLY AFTER DIVIDING
INTO STRIPS ORBLOCKS,SUCHAS TWO-WAY ORTHOGONAL LATTICED GRIDS,ORTHOGONAL SQUARE
PYRAMID SPACE GRIDS, AND THE THOSE WITH OPENINGS. THE SIZE OF EACH UNIT WILL DEPEND
ON THE HOISTING CAPACITY AVAILABLE.
24. •THE WHOLE SPACE FRAME IS ASSEMBLED AT GROUND LEVEL SO THAT MOST OF THE WORK CAN
BE DONE BEFORE HOISTING. THIS WILL RESULT IN INCREASED EFFICIENCYAND BETTER QUALITY.
FOR SHORT AND MEDIUM SPANS, THE SPACE FRAME CAN BE HOISTED UP BY SEVERAL CRANES.
• FOR LONG-SPAN SPACE FRAME,TEMPORARY POSTS ARE USED AS THE SUPPORT AND ELECTRIC
WINCHES AS THE LIFTING POWER.THE WHOLE SPACE FRAME CAN BE TRANSLATED OR ROTATED IN
THE AIR AND THEN SEATED ON ITS FINAL POSITION. THIS METHOD CAN BE EMPLOYED TO ALL
TYPES OF DOUBLE-LAYER GRIDS.
25. •THE SPACE FRAME GRID GEOMETRY TAKES 5
GEOMETRIC OPERATIONS TO CREATED THE
CORRESPONDING GRID TO ULTIMATELY CREATED

•THE VERTICES ON THE GRID(GI) ARE CONNECTED
TO IDENTIFY THE 3 DIMENSIONAL JOINT(3DN) AND
BY CONNECTING THE 3DN THE SEMI-REGULAR IS
CONSTRUCTED.

Given the uniform distribution of points in such a lattice, plus the equal distances between each point and its 12 nearest neighbors, Fuller
called this the isotropic vector matrix (IVM) used it to think about situations with everywhere-the-same energy conditions (what "isotropic" means).
The cctet truss is simply the IVM realized as an artifact for use in engineering applications. These applications range in size from the
nanotechnological to the mega-structural -- or any scale in between
