An example is included in which the behavior of an existing steel moment frame designed by conventional elastic method is modified by introducing an opening in the beam webs with added web members in order to achieve a desired yield mechanism. 4 Substructure and Foundation Loads Figure 7. The role of plastic analysis in seismic design are illustrated in the following two examples. The 1976 Uniform Building Code (UBC) is probably the first code (and the only present code) to set a drift limit. Therefore, there is a need to further evaluate the impact of redundancy in the seismic design and. 3) For structures assigned to Seismic Design Categories D, E, or F, the following types of. seismic design: the activities necessary to demonstrate that a piping system can perform its intended function (position retention, leak tightness, operability, or a combination) in case of design earthquake; seismic function: a function to be specified by the engineering design. Earthquake Resistant Design According To 1997 UBC Major Changes from UBC 1994 (1) Soil Profile Types: The four Site Coefficients S1 to S4 of the UBC 1994, which are independent of the level of ground shaking, were expanded to six soil profile types, which are dependent on the seismic zone factors, in the 1997 UBC (SA to SF) based on previous. Today, major building codes and seismic design guidelines exist which address seismic design forces for various nonstructural components. Therefore, there is a need to further evaluate the impact of redundancy in the seismic design and. EUR 25204 EN - 2012 Eurocode 8: Seismic Design of Buildings Worked examples Worked examples presented at the Workshop "EC 8: Seismic Design of Buildings", Lisbon, 10-11 Feb. The presented example is a three-bay three-storey steel braced frame. In seismology, a seismic zone is an area of seismicity potentially sharing a common cause. 2D + f1L + 1. Dynamic Design Base Shear For dynamic analysis, the 1994 UBC requires that the “design base shear”, V, is to be evaluated from the following formula: V = [ Z I C / RW ] W (17. 1) require ω = 1. 9 Design Example Consider a small building with a plan dimension of 150 feet by 70 feet. 3-01), the seismic forces in this standard should be reduced by the applicable factors to derive comparable forces at allowable stress levels. of seismic design required for a structure, depending on the intensity of design ground motions, and the structure’s occupancy/use, and therefore acceptable risk. of the base area, so that the footing is subjected to concentric loading, resulting in uniform bearing pressure. 4 ASCE 7-98/02 and ASCE 7-05 D2. xls OMRF-UBC. 5) Where V= total seismic lateral force at the base of the structure W= total seismic load - In storage and warehouse occupancies, a minimum of 25 % of floor live load is to be considered.

How Seismic Design Categories Are Determined The seismic design category must be specified by a professional engineer or registered architect on the project drawings per ASCE 7. Some areas will have much higher seismic design forces, some will have much lower forces, and some will be about the same. In the 1997 edition of the NEHRP Provisions, the seismic design category (SDC) of a structure, which is based on occupancy as well as on soil-modified seismic risk at the site of a structure, determines the level of detailing and design. Seismic Design of Steel Special Moment Frames: A Guide for Practicing Engineers Structural steel special moment frames often are used as part of the seismic force-resisting systems in buildings designed to resist earthquakes with substantial inelastic energy dissipation. UBC97 - Seismic Base Shear Calculation Procedure UBC 97 Seismic Base Shear Calculation Steps are as follows 1. If the component of the project is required to function for life-safety purposes after an earthquake (including fire protection sprinklers), if the component contains hazardous materials, or if the component is in or attached to an Occupancy.

It's very likely that some of the non-specific "Zone 4" requests are IBC High Seismic Area requests, simply using the old UBC "Zone 4. Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections.
