Consider a reinforced concrete building frame (beams and columns) with concrete shear walls (between and integral with the columns) designed for seismic resistance per ASCE 7-05 in SDC C or worse. Can this system be classified as a "B. Building Frame System" per Table 12.2-1 or MUST it be classified as a "D. Dual Systems with special moment frames...", or "E. Dual System with intermediate..." Systems D and E will require a more complex analysis particular for higher SDCs. I do not need a "dual system" but I am not sure if "B" can be used due to the presence of the moment frame. Can anyone site a reference that clarifies this? I have not found one.

As the semiconductor industry races to keep pace with Mooreâ€™s Law, which regards the doubling of transistors per square inch on integrated circuits, lithography hardware systems are not always able to provide a quality image for creating circuits. Download Now
Current integrated circuit (IC) designs are complex, which can result in different voltages being located close to one another. To prevent time dependent dielectric breakdown (TTDB), it is essential to incorporate space rules within IC design. Download Now
