During the past earthquakes, different low ductile failure modes are observed in the gravity design structures and thus, the most of existing damage indices may fail to assess the damage of gravity design structures accurately in referring to the two main performance levels: immediate occupancy and ultimate limit state. Therefore, this study investigates the energy dissipated by the brittle structures and the possible damage indices based on energy for the damage assessment of gravity design frames. In the framework of an Energy-Based Seismic Design Approach, we need the assessment of the Demand and on the Capacity, both expressed in Energy. A methodology for the assessment of the seismic energy demands imposed on structures is already proposed, but not such methodology that makes consensus is proposed for the calculation of the Energy dissipation Capacity avoiding the Hysteretic models. The estimation of the energy expended by the building during an earthquake excitation is a tricky issue. For this purpose, this study considers the wavelet based energy estimation and compares it with different approaches for measuring the damages of a structure: the dominant inelastic period of a building and the more classical measure, the inter-story drift. IDA analysis are performed in energy, drift and inelastic period. Furthermore, the damage assessment results based on the expended energy for three gravity design buildings are compared and discussed relatively to the results expressed in inelastic period and drift. Finally, this study concludes that no significant effects of number of inelastic cycles to the damage assessment results for low ductile structures. However, this study also highlights the effects of number of inelastic cycles to the damage for medium and high ductile structures.

Malawi is located within the southern branch of the active East African Rift System, where earthquakes of Mw 7.0 (or greater) can occur along major faults. In Malawi, the majority of dwellings in both formal and informal settlements are non-engineered unreinforced masonry constructions, built by local artisans with little input from engineers. These constructions are highly vulnerable to seismic events due to poor materials and lack of construction detailing. This study develops analytical vulnerability functions that enable the assessment of seismic capacity of typical buildings in Malawi. Since the seismic vulnerability greatly depends on building characteristics, geometrical and structural data are collected by conducting semi-rapid surveys of 300 houses located in urban and rural areas of Central and Southern regions of Malawi. Mechanical properties of the local materials are also obtained from an experimental campaign. In this work, a mechanical method FaMIVE (Failure Mechanism Identification and Vulnerability Evaluation) is adopted and the effects of both in-plane and out-of-plane behaviour of the masonry structures are taken into consideration to derive capacity curves for seismic vulnerability assessment. Special attention is given to 1) the Malawian building typologies as described in the Word Housing Encyclopedia and 2) failure mode classes for the Malawian constructions as calculated by FaMIVE. Hence, the derived vulnerability functions can serve as a benchmark for typical buildings in Malawi. The results and conclusions are also relevant for other East African countries, where similar construction techniques are adopted.
马拉维位于活跃的东非裂谷系统的南部分支，在那里沿主要断层可以发生7.0级(或更大)的地震。在马拉维，正式和非正式住区的大多数住宅都是未经工程设计、未经加固的砖石建筑，由当地工匠建造，很少有工程师的投入。这些建筑非常容易受到地震事件的影响，因为材料差，缺乏建筑细节。本研究开发了分析易损性函数，使马拉维典型建筑物的抗震能力评估成为可能。由于地震脆弱性在很大程度上取决于建筑特征，几何和结构数据是通过对马拉维中部和南部地区城市和农村地区的300所房屋进行半快速调查来收集的。通过实验获得了局部材料的力学性能。本文采用FaMIVE (Failure Mechanism Identification and Vulnerability Evaluation)力学方法，综合考虑砌体结构面内、面外特性的影响，推导出抗震易损性评价的能力曲线。特别要注意的是:1)世界住房百科全书中描述的马拉维建筑类型;2)FaMIVE计算的马拉维建筑的失效模式等级。因此，推导出的脆弱性函数可以作为马拉维典型建筑的基准。结果和结论也适用于其他东非国家，这些国家采用了类似的建筑技术。
