九二一集集地震磚造歷史街屋震害調查研究

本文調查九二一集集地震受損的四個磚造歷史街屋，以瞭解磚造歷史街屋在強烈地震作用下之災損現象及其影響因素。四個調查研究之歷史街屋為（一）南投市民權街（二）竹山鎮竹山路及集山路一段（三）斗六市太平路（四）田中鎮中州路及員集路。主要震害現象有下列幾點：1.女兒牆（簷牆）及臨街牆面斷裂或翻落極為普遍2.騎樓為街屋單元耐震上之弱點3.同一街屋群組中，角間及邊間損壞較其他單元嚴重4.上部木造與整體磚造街屋之震害模式有明顯差別5.同時興建之街屋群組震害較小。這些現象與1930年台南州地震及1935年屯子腳地震街屋震害相比，現象大致類似。經由本次之調查研究，發現歷史街屋主要震害原因除了主體為脆性構造材料外，與街屋結構系統有密切之關係，建築師及修護者在震後街屋修復及規劃設計再利用時，應先瞭解其材料及系統特性，然後針對該街屋建築之震現象做妥善之原因分析及對策考慮。

For investigating the seismic performance and damage of brick-work historic shop-houses, several historic streets located in Nantou City, Jushan Town, Douliou City, Tianjung Town were surveyed after the September 21, 1999, Chi-Chi earthquake The major damage types have following: 1. Parapets and walls facing street crack and drop down are very popular. 2. Gallery is a seismic weak point of the shop-house. 3. The edge or corner unit gets damage more seriously than other units. 4. The damage of unit with wood or bamboo stucco wall on the second floor is different from total brick construction. 5. The damage of group built is not so serious as that built individually in different period. In general these damage types, are similar to that damaged in the 1930 Tainan Earthquake and the 1935 Hsinchu-Taichung Earthquake. For architects and conservation engineers, the damage experienced in Chi-Chi earthquake should be served as the lesson when they do the retrofitting or reusing design of historic shop-houses.
