Instructional Material Complementing FEMA 451, Design Examples Design Concepts 7 - 4 Seismic Design Practice in the United States continued • For reasons of economy and affordability, the design forces are much lower than those that would be required if the structure were to remain elastic. This resource page provides an introduction to the concepts and principles of seismic design, including strategies for designing earthquake-resistant buildings to ensure the health, safety, and security of building occupants and assets.The essence of successful seismic design is three-fold. This moment level is labeled as probable flexural strength, Mpr. With easy-to-understand explanations of the basic concepts, Seismic Design of Foundations examines recent and worldwide research outputs and post-earthquake reconnaissance case studies and offers practical means of applying them to the real world. This seismic design and analysis methodology as presented here was developed for offshore pipeline design. During the 1995 Kobe earthquake, the Hanshin Expressway Kobe Route was subjected to near-field strong ground motions, resulting in serious damage to a large portion of the Kobe Route. 1998. EARTHQUAKE-RESISTANT DESIGN CONCEPTS 4.2 Nonbuilding Structures The NEHRP Recommended Seismic Provisions also includes seismic design crite-ria for many structures that are not considered to be buildings. Seismic Design Concept 1 Ductility Design • A Reduced Design Seismic Force Can Be Used IF Sufficient Ductility Is Built into the Structure • But Only a Certain Elements Are Strategically Designated to Serve as Structural Fuses, i.e., Deformation-Controlled Elements (DCE) It has been successfully applied in seismic analyses of buried pipelines under fault crossing and unburied pipelines with a subsea manifold by using a static analysis and a dynamic time history analysis. design have now matured to the stage where seismic assessment of existing structures, or design of new structures can be carried out to ensure that particular deformation-based criteria are met. The paper will outline and compare the three methods, and discuss them in the context of The focus of discussion is on design concepts and issues more routinely used or encountered by structural engineers during seismic design of new or retrofitted pile foundation systems representative of those used for bridges and buildings. Earthquake-Resistant Design Concepts An Introduction to the NEHRP Recommended Seismic Provisions for New Buildings and Other Structures FEMA P-749 / December 2010 (Reference is made to (31).) 14.3 Conclusions. First, the design team must take a multi-hazard approach towards design that accounts for the potential impacts of seismic forces as well as all the major hazards to which an area is vulnerable. : 244- 8011 email.

Cyclic behaviour on cement and concrete; Ductility properties of beam; Ductility Design; Tectonic Plate. Seismic Design of Foundation: Concepts and Applications justifies its title by delivering a solid exposition of theory along with practical worked out examples that are required for designing the foundations of different structures like buildings and bridges subjected to seismic loading. Download Citation | New concept of structural seismic design: earthquake resilient structures | Earthquake resilient structure is a new branch of the seismic structural design. Correct design concept The correct approach is to select an anchor that is suitable for use under seismic conditions and to design it as per current available literature or standards for given design conditions. Module Format ... Today, the principles of capacity design together with the concepts of ductile behavior allow a safe and cost effective earthquake resistant design. In any real-world situation, it is important to seek proper advice from a professional structural engineer before any work is undertaken. Basic concepts for seismic design codes are outlined with special emphasis on the role of ductility. This module is intended for an engineer unfamiliar with structural dynamic concepts for seismic design. Thomas Telford Ltd., London) Keywords There are several fundamental concepts that the designer can draw on to achieve this goal. 1.5 Force-based Design to Displacement-based Design 13 2 Earthquake Demand on Buildings 2.1 Seismic Design Force 15 2.2 Dynamic Characteristics of Buildings 18 2.2.1 Natural Period 18 (a) Fundamental Natural Period of Building 19 (b) Factors influencing Natural Period 20 (1) Effect of Stiffness 21 (2) Effect of Mass 22 Seismic design concepts ; Braced frames; Braced frames. There are several fundamental concepts that the designer can draw on to achieve this goal. A degree of seismic resilience can be achieved by applying a sound understanding of structural engineering and construction principles to the structural elements and system that make up the building. : m-ali@uiuc.edu CAMPUS HONORS COURSE CHP 295 EE: Reducing Earthquake Consequences October 8 … In each case, the nuances, complexities and engineering understanding that make these systems feasible in practice has been simplified. The design base shear is derived from a modified energy balance equation incorporating the concept of seismic force reduction factor and the displacement amplification factor. A description of the effects of the Liège earthquake (November 8, 1983) on structures is not subject of this paper. Earthquake-Resistant Design Concepts. seismic design shear forces. There are six SDCs rang- ing from A to F with structures posing minimal seismic risk assigned to SDC A and structures posing the highest seismic risk assigned to SDC F. An Introduction to the NEHRP Recommended Seismic Provisions for New Buildings and Other Structures. •Seismic requirements safeguard against major failures and loss of life– they DO NOT necessarily limit damage, maintain function, or provide for easy repair. Seismic design concepts A degree of seismic resilience can be achieved by applying a sound understanding of structural engineering and construction principles to the structural elements and system that make up the building.

Seismic load path and dynamic behaviour of multi-storey structure; Please note this module is not aimed to comprehensively teach ALL concepts related to dynamic concepts for Seismic Design. Seismic Conceptual Design of Buildings – Basic principles for engineers, architects, building owners, and authorities Hugo Bachmann. Some new concepts of seismic design were adopted in this code by drawing on the lessons of the 1995 Kobe earthquake that caused devastating damages. 236. Seismic design shear Ve in plastic hinge regions is associated with maximum inelastic moments that can develop at the ends of members when the longitudinal tension reinforcement is in the strain hardening range (assumed to develop 1.25 fy).

Seismic Design - Design Concepts (PDF) CEB Bulletins No. Krakowska 6a 05-090 Janki k/Warszawy Real buildings usually integrate several different techniques at the same time to limit seismic forces, and a typical medium or high-rise reinforced concrete structure, for example, may use several of these concepts at the same time. Seismic Design in Steel -- Concepts and Examples (Part 1): Introduction to Effective Seismic Design (R1) This 8-part course is intended to provide engineers with guidance on applying the AISC seismic design requirements, correctly and efficiently, on typical projects in regions of moderate or high seismicity. uses the Seismic Design Category (SDC) concept to categorize structures according to the seismic risk they could pose. 5 GENERAL CONCEPTS OF EARTHQUAKE RESISTANT DESIGN bedded or tied into the main struc-ture of the building. INTRODUCTION The intent of this paper, is to focus on design concepts Kontakt. There are two main varieties of braced frames – concentric and eccentric. Another fundamental concept in engineering – bracing – involves added additional elements to a frame in order to increase its ability to withstand lateral loads. Seismic Design Practice in the United States •Seismic requirements provide minimum standardsfor use in building design to maintain public safety in an extreme earthquake. Earthquake Engineering: Deffinitions; Basic of Seismic Design concepts; Ductility Properties. A degree of seismic resilience can be achieved by applying a sound understanding of structural engineering and construction principles. Designing a building is a complex and specialist undertaking that is well beyond the scope of this guidance, but a few of the basic concepts are briefly introduced here. These principles govern primarily the: • Conceptual design, and the • Detailing of • Structural elements and • Non-structural elements The conceptual design and the detailing of the structural elements (walls, columns, slabs) and … ARCHITECTURAL SEISMIC DESIGN CONCEPTS Instructor: Dr. Mir M.
