A roof or floor diaphragm in a wood building generally spans across multiple lateral force-resisting elements (shear walls). The diaphragm serves as a horizontal beam that distributes forces to the shear walls. For design purposes, it is common to assume the wood diaphragm is either completely flexible or completely rigid. In North American low-ris...

This paper presents a beam-spring analog model for use in seismic analysis of wood diaphragms in North American style light-frame wood construction. A roof or floor diaphragm in a wood building generally spans across multiple lateral force resisting elements (shear walls). The diaphragm serves as a horizontal beam that distributes forces to the she...
Article
Based on previously developed evaluation criteria, a serviceability limit state is established for reliability analysis of building damage caused by excavation. The term damage is defined herein as the violation of service-ability requirements such as exceeding the threshold principal strain in the building. In this paper the model uncertainty or m...

The hysteretic behavior of wood shear walls subjected to cyclic loading exhibit highly nonlinear force-displacement responses. There exists a careful balance between model complexity and necessary accuracy. In fact, the most widely used models for hysteretic behavior utilize piecewise-linear functions with static parameters to model the nonlinear h...

In the United States the vast majority of single and multifamily homes are constructed using light-frame wood construction which typically consists of dimension lumber sheathed with plywood or oriented strand board. These structures resist lateral loads such as those produced by wind or earthquakes by a system of wood shear walls. One widely used d...
Article
Wood shearwalls provide the majority of the lateral force resistance in light-frame wood construction, which makes up the vast percentage of residential and some percentage of commercial construction in the United States. One of the objectives of a recent Structural Engineering Institute (SEI) special project entitled "Re-evaluation of LRFD for eng...
Article
The procedures underlying the load and resistance factor design (LRFD) format for engineered wood construction combine elements of reliability analysis with the experience gained from decades of successful use of allowable stress design procedures. However, the judgments applied in much of the early development or LRFD hinged directly on the load f...
Conference Paper
In the United States the vast majority of single and multi-family homes are designed and built using light-frame wood construction. These structures resist lateral loads, i.e. wind or earthquake induced, primarily through a system of wood shearwalls. The LRFD design standard for the construction of wood shearwalls is AF&PA/ASCE 16. The purpose of t...
Conference Paper
This paper presents selected results from a study to assess the reliability of wood members designed in accordance by current LRFD procedures.

... Because the building codes for residential LWFS structures are prescriptive, there is sometimes minimal engineering basis for the design approach. Recent interest has focused on developing performance based design methodologies for LFWS that will provide more risk consistency and better reliability of LFWS ( Crandell et al. 2006;Ellingwood et al. 2006; van de Lindt and Dao 2009). To further this goal, experimental studies are underway to develop better understanding of the interaction of loads with the complex structural systems in a wood-framed house to understand the system performance of the whole system. ...
... One of the first examples of comprehensive research projects aimed at studying the dynamic properties and seismic performance of the LFW technology is represented by the CUREE Project (Filiatrault et al. 2000(Filiatrault et al. , 2001Gatto and Uang 2002), where extensive testing on LFW structures (including shake-table testing of full-scale buildings) was performed. Shake-table tests on two-story and six-story LFW buildings were also carried out within the NEESWood project, devoted to the development of a performance-based seismic design (PBDS) approach and to the safety and mitigation of damage to low-rise wood-based buildings in the seismic zones of the USA ( Van de Lindt et al. 2008Filiatrault et al. 2009). In Europe, a significant contribution to the understanding of the seismic response of LFW systems was given by the research carried out by several research institutes. ...
... In practice, this means that the seismic analysis is generally performed using simple beam approximations and a force-based approach from the Building Code. State-of-the-art approaches include various FEM non-linear methods with 2-D beam-spring models [2], considering the behavior of each nailed connection [3] , linear and non-linear 3-D analysis using traditional shell ele- ments [4,5], a specialized 2-D diaphragm finite element [6], and models considering the influence of beam pocket behavior [7,8]. Direct Displacement Based Seismic Design (DDBD) procedures are a less computationally intensive alternative to FEM non-linear analyses. ...
... Parameters influencing shear strength of the shear walls: the bearing capacity, inter- nal stressing, geometric and material properties are pre- sented in analysis method proposed in paper of Kassem and Elsheikh (2010). Tests programs demonstrating how the mid-rise wood-frame buildings respond to a dynamic loading and results of test of full-scale buildings are in- cluded in papers of Van de Lindt et al. (2010aLindt et al. ( , 2010b, Pei et al. (2013), Van de Lindt et al. (2013). Building performance and global drift of structure under dynamic load was evaluated on the damage inspections of walls. ...
... The aftermath of such recent natural disasters and the potential for higher losses in the future, especially in areas where building practices have neglected the potential effects of such natural hazards, and has led to recent scrutiny of real or perceived deficiencies in design and construction practices, building codes, and their enforcement ͑Rosowsky and Ellingwood 2002;NAHB 1993NAHB , 1994Rosowsky et al. 2003͒. This scrutiny has pointed to the need for tools to assess the condition of the current residential building inventory and its vulnerability to future hazards. ...
... In the United States, the timber engineering design and research communities are in the process of developing new design guidelines and procedures that will enable building taller woodframe structures with confidence, including those in seismic regions such as the Pacific Northwest where wood has a strong industry hold. One such effort is the NEES- Wood project which focuses on the development of a performance-based seismic design PBSD procedure for midrise woodframe construction in regions of moderate to high seismicity van de Lindt et al. 2006. As part of the NEESWood project, a series of full-scale seismic tests of a two-story Benchmark Woodframe Building was conducted at the Univ. ...
... For excavation-induced deformations, Boscardin and Cording (1989) correlated damage to brick bearing walls and small frames with a combination of horizontal strain and angular distortion for building damage assessment. Schuster et al. (2008) defined "damage" as the violation of serviceability, e.g. exceeding an assumed threshold of angular distortion or strain. ...
... It is now well recognized that natural soil properties exhibit spatial variability because of depositional and postdepositional processes. e inherent variability in soil properties has found its place in geotechnical design and has been extensively incorporated in the analysis of slope stability [1][2][3][4][5], foundation bearing capacity [6,7], foundation settlement [8][9][10], and liquefaction [11][12][13]. A lognormal distribution has been generally accepted in a geotechnical reliability analysis [14][15][16] because of its capability to model the randomness of positive soil parameters. ...
... However, this approach is difficult to be implemented in a multiple-dimension space such as using both CPT and V s measurements. Rather, searching technique, proposed by Juang et al. [39], is a more objective approach for establishing limit state function that can be used in multiple-dimension space. In the present study, the searching technique with aid of PSO-KELM is adopted to search the nonlinear relationship between CRR and CPT along with V s measurements. ...
... In the analyses, the software ABAQUS was used to simulate the behavior of I beams which are modeled as anisotropic elastic plastic composite beams. In the finite element studies, generally beam elements for frame members, shell elements for OSB panels and springs for connector elements are used [24,[26][27][28]. Furthermore, diagonal strut approach is used to simulate the behavior of timber panels and to develop the mathematical models [4]. ...
