1、Designation: E 2127 01a (Reapproved 2007)Standard Methods ofStatic Load Test for Combined Tensile and Transverse LoadResistance of Paneled Wall Systems in BuildingConstruction1This standard is issued under the fixed designation E 2127; the number immediately following the designation indicates the y
2、ear oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover the procedures for determin
3、-ing the resistance of paneled wall systems subjected to com-bined lateral loads and axial loads.1.2 These test methods involve the simultaneous applicationof transverse (lateral wind) and tensile (wind uplift) loads topaneled wall system assemblies anchored at both ends withhold-down connectors.1.3
4、 These test methods are suitable for determining thestructural adequacy of the design, system, and wall fabricationtechnique, and are not intended to evaluate the strengthcapacity of the hold-down connectors.1.4 This standard does not purport to address all of thesafety concerns, if any, associated
5、with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Terminology3.1 DefinitionsFor definitions of general terms used inthis test method, refer to Terminology E 631.4. Summary of Test Method4.1 The tensile and bending capacity of the paneled wallsystem
7、 is determined by applying a simultaneous tensile andtransverse load to a wall specimen. This is accomplished byanchoring one end of the specimen and applying a tensile loadto the opposing end while applying a transverse load; see Figs.1 and 2. The forces required to deflect the specimen and thecorr
8、esponding displacements at each load interval are mea-sured.5. Significance and Use5.1 The procedures described will test the behavior ofsegments of paneled wall system construction under conditionsrepresentative of those encountered in service. Performancecriteria based on data from those procedure
9、s can verifystructural adequacy and service life.6. Test Apparatus6.1 Test Assembly:6.1.1 GeneralTests shall be made on three like specimensfor each orientation. All system elements shall be fastened in amanner to conform with the wall specifications. The wallsystem shall be representative of actual
10、 building construction.6.1.2 ConnectionsThe performance of the wall is influ-enced by the type and spacing of the anchoring to the upper andlower ends of the wall.6.1.3 Paneled Wall System RequirementsThe paneledwall system specimen shall be comprised of members andconnectors representative of those
11、 used in building construc-tion, except that the specimen is permitted to consist of a coreon which paneled wall system surface units are placed.6.1.4 Test SetupThe paneled wall system specimen shallbe tested vertically or horizontally so that surface units may beobserved during the test. The test f
12、ixture shall allow forsimultaneous transverse and tensile load application. The topand bottom of the specimen shall be attached to rigid supports.6.1.5 Paneled Wall System SizeThe paneled wall systemspecimen height shall not be less than the actual height of thewall, and the width shall be minimum 4
13、8 in. (120 cm) wide, orthe width of an individual wall panel (if the individual panelwidth is greater than 48 in. wide).7.
