Curtain wall support method and apparatus

Abstract: A curtain wall (ACM) system has vertical mullions and horizontal supports which provide a dry as well as a structural system for non-sequential construction of curtain wall exteriors. Internal gutters offer a failsafe moisture proof system. The horizontal and vertical framework members may be mounted in the reverse orientation for special exterior wall configurations. Individual panels can be replaced without sealants or tear down of neighboring panels. A face support for the thin ACM panels is provided. Thermal expansion is addressed with a floating panel on a track design. Alternate embodiment includes transition frame members having glass and metal panel integral supports, freestanding X-Y sub-frame assemblies, fiber optic outboard channels and novel methods of assembly.

Dynamic Racking Performance of an Earthquake-Isolated Curtain Wall System:

Abstract: Dynamic racking tests, coupled with air leakage tests, were performed on fullsize specimens of a new, Earthquake‐Isolated Curtain Wall System and a widely used, conventional curtain wall system (used as an experimental control) Dynamic racking tests simulated seismic movements that could be imposed upon a curtain wall system as a result of interstory drifts Air leakage tests were performed as an indicator of serviceability performance of both curtain wall systems during the dynamic racking tests The Earthquake‐Isolated Curtain Wall System demonstrated strongly superior performance in terms of both serviceability (glass cracking and air leakage) and life safety (glass fallout) The conventional system exhibited vulnerability to annealed monolithic glass cracking and glass fallout at dynamic racking drift indices of 19% and 31%, respectively No glass damage was observed in the earthquake‐isolated system up to the dynamic racking displacement limit of the test facility, which corresponded to a

Wind-Induced Torsional Loads and Responses of Buildings

Abstract: Wind-induced loads on a building are invariably spatially non-uniform and some twisting about its vertical axis results. The magnitude of this wind-induced moment or torque depends on the shape of the building, the influence of surrounding buildings and the direction of the wind. Even for symmetrical plan forms such as a squares or a rectangular in homogeneous surroundings, torsional forces occur when the direction of the wind is not along a line of symmetry. The wind-induced torque is accentuated in the presence of eccentricities between the effective centres of rigidity, mass and aerodynamic force and for buildings with relatively long torsional periods of vibration. Torsional effects can substantially increase wind-induced loads on the main wind force resisting system; accentuate the racking of exterior walls and therefore influence the detailing of the curtain wall system; and add to the wind-induced motions, which if excessive can adversely affect occupant discomforts. Despite its importance, wind-induced torsion is overlooked or at best dealt with in a nominal fashion by most building codes. The National Building Code of Canada and more recently ASCE Standard 7 require designers to consider partial as well as full wind loading. In the partial load case, the wind loading on any portion of the building is reduced by 25% for buildings over 60 feet. This results in a wind- induced torque which corresponds to a base shear eccentricity of just under 4% of the building width. This is far short of actual eccentricities for some buildings, predicted from wind tunnel model tests and empirical data bases. While the effects of torque on the structural frame are seldom dominant, they can substantially alter the distribution of the wind-induced forces. If not allowed for in design, this has the effect of diminishing the effective safety index of some parts of the structural frame. Torsional load effects are not the domain of tall buildings alone and significant eccentricities of wind-induced forces also occur for low and intermediate height buildings. The effects of wind-induced torque are discussed for buildings of tall, intermediate and low height.

Coupling apparatus with parallel members joined by an elastic or spring element pivotally interfacing a drywall and curtain wall mullion

Abstract: A building includes a coupling apparatus providing an interface between a drywall and an exterior curtain wall mullion.

Insulating material may be placed between the first and second members to provide sound insulation. The coupling apparatus permits inward and outward movement of the exterior curtain wall with respect to the drywall during windy conditions and side to side movement of the exterior curtain wall with respect to the drywall during earthquake conditions.

Glass curtain wall structure

Abstract: The utility model relates to a glass curtain wall structure. Aluminum alloy glass curtain walls at present usually use silica gel or screws and rivets as force transmission media, which have poor abilities of wind resistance and earthquake resistance. The glass curtain wall structure with aluminum alloy frame chase mortise structure of the utility model doesn't use screws or rivets, but uses shaped aluminum profile.

The structure of the utility model designs and invents a basic member which is composed by combining the shaped aluminum profile and the mortise connection iron member of the chase mortise. The utility model is welded and connected into integration by transition connection steel plates and pre-buried members of buildings. The mechanical property of the utility model is good. The rabbet for connection forms an elastic fulcrum in the groove of the aluminum profile. Therefore, the utility model has good effect of force dissipating, and the abilities of wind resistance and earthquake resistance can be improved.

Thermal barrier for use on the front flange of a mullion in a curtain wall

Abstract: The thermal barrier is used on a flange projecting out from the front portion of a mullion in a curtain wall. The curtain wall comprises horizontal and vertical mullions defining a plurality of subsections, each enclosing a windowpane. This thermal barrier comprises a front section and two side sections transversally projecting from opposite edges of the front section. The front and side sections define a flange-receiving housing. The thermal barrier is shaped and sized so th at a rear edge of at least one side section is in a positive engagement with the fr ont portion of the mullion when the thermal barrier is installed over its flange. Th is thermal barrier replaces the conventional thermal barrier without changing the structural resistance of the curtain wall. It provides an improved thermal insul ation and corner plugs are no longer necessary to fill the spaces between perpendicula r flanges. Smaller amounts of caulking are also required to seal the space created by the expansion joint between two vertical mullions since that space is much smaller than the one left by conventional thermal barriers. The installation of the curtain wall is thus simplified and more rapidly completed. The quality of the w ork is also likely to be more constant. A further advantage is that each thermal bar rier entirely covers the flange so that a windowpane, during its installation in a subsection, is less likely to be damaged since the edges thereof never directly make contact with the hard aluminum interior surface of the flanges.

The building surface materials, the curtain wall materials, and four corners of the structural frames are inserted into the clamping holders of the assembly in sequence. Consequently, the utility model realize the installation of building surface materials and curtain walls. The utility model has the advantages of simple technical process, low cost, short construction period, and beautiful appearance, and can form commercialization production by the installation.
