利用一个5层的平面和立面不规则结构，以及一个15层和一个20层的平面不规则结构，在地震荷载作用下，比较了8组不同的调谐质量阻尼器（TMD）参数调整方程。其次，双向调谐质量阻尼器（BTMD）的性能进行了比较，摆调谐质量阻尼器（PTMD）使用三个不同的结构，平面和垂直不规则的高度从5到20层，主要的基本周期从0.55秒到4.25秒受到洛马普列塔地震。结果表明，BTMD在减小最大位移、加速度和基底剪力方面始终优于PTMD。BTMD优于PTMD，因为它可以针对两种振动模式进行调谐，因此可以用作使用两种TMD的替代方案。然后，使用一个20层的建筑结构，平面不规则的BTMD的有效性进行了研究，受到六个地震加速度。最后，BTMD的最佳位置进行了研究，使用五个不同的多层建筑结构的平面和高程不规则性范围内的高度从5到20层和基本周期范围从0.55秒到4.25秒受到洛马普列塔地震。这套会议记录是根据2002年12月4日至6日在香港举行的建筑技术进步国际会议编写的。这两卷会议录包含9篇特邀主旨论文、11个团队提交的72篇论文以及来自世界各地20多个国家的133篇投稿论文。这些论文涵盖了结构和建筑、环境和信息技术三个技术子主题的广泛主题。这些类别中的多样性跨越了主题的宽度，这些会议记录为读者提供了建筑研究最新进展的良好概述。这本书是一个最新的来源计算应用程序的优化，预测通过人工智能方法，并评估元启发式算法与不同的结构应用。元启发式算法作为当前研究的热点之一，受到了广泛的关注
Eight different sets of equations proposed for tuning the parameters of tuned mass dampers (TMDs) are compared using a 5-story building with plan and elevation irregularity, and a 15-story and a 20-story building with plan irregularity subjected to seismic loading. Next, the performance of bidirectional tuned mass damper (BTMD) is compared with that of the pendulum tuned mass damper (PTMD) using three different structures with plan and vertical irregularities ranging in height from 5 to 20 stories and dominant fundamental periods ranging from 0.55 sec to 4.25 sec subjected to Loma Prieta earthquake. It is concluded that BTMD performs consistently better than PTMD for reduction of maximum displacement, acceleration and base shear. BTMD is advantageous over PTMD because it can be tuned for two modes of vibrations and therefore can be used as an alternative to using two TMDs. Then, the effectiveness of BTMD is investigated using a 20-story building structure with plan irregularity subjected to six seismic accelerograms. Finally, the optimal placement of the BTMD is investigated using five different multi-story building structures with plan and elevation irregularities ranging in height from 5 to 20 stories and fundamental periods ranging from 0.55 sec to 4.25 sec subjected to Loma Prieta earthquake. This set of proceedings is based on the International Conference on Advances in Building Technology in Hong Kong on 4-6 December 2002. The two volumes of proceedings contain 9 invited keynote papers, 72 papers delivered by 11 teams , and 133 contributed papers from over 20 countries around the world. The papers cover a wide spectrum of topics across the three technology sub-themes of structures and construction, environment, and information technology. The variety within these categories spans a width of topics, and these proceedings provide readers with a good general overview of recent advances in building research. This book is an up-to-date source for computation applications of optimization, prediction via artificial intelligence methods, and evaluation of metaheuristic algorithm with different structural applications. As the current interest of researcher, metaheuristic algorithms are a high interest
