The Wenchuan earthquake occurred on May 12, 2008 (Beijing Time) caused great economical loss and large amount of buildings were destroyed. Many of single-story reinforced concrete industrial buildings in Hanwang town located in the highly seismic region were damaged, and the damaging phenomenons are very typical. According to the damage survey and analysis of typical seismic damage for the single-story reinforced concrete industrial buildings located in Hanwang town, the damage distribution and failure characters of these buildings are summarized in this paper. The single-story reinforced concrete industrial buildings which were designed according to current seismic design code have better earthquake resistant behavior than those old single-story reinforced concrete industrial buildings and the damaging phenomenon show some new features. Finally, combining current seismic design code of our country and the earthquake damage lessons, some reasonable suggestions on the work of seismic strengthening and earthquake resistant design of the single-story reinforced concrete industrial buildings have been given.

Based on the damage field survey of the industrial building in Wenchuan earthquake, the typical building seismic damage characteristics of industrial structures were summarized and analyzed. According to the damage phenomenon, the following conclusions are derived: usually, the main structures of industrial buildings received serious damage, which roof system were distorted and collapse, bent-frame column were pressed and yielded, bracing system were tension broken or pressed and yielded; when the main structures of industrial building received minor damage, the non-structural member regular suffered relatively damage, include the end bays in the longitudinal direction, high gables, the cantilevered walls between two span with different height and the foundation. Then damage rules and reasons are summed up and damage characteristics and the corresponding design and retrofitting suggestion are proposed. At the end of the paper, it was indicated that seismic design of major structure and non-structural members of factory building must be fully complied with the Seismic Design Code, seismic assessment and seismic strengthening should be carried out at regular intervals for the existed industrial building, which served a long time and whose fortification level is unsatisfied with requirement.

This paper presents an evaluation study of the performance of reinforced concrete arch bridge structures under earthquake load. The study is aimed to investigate the seismic performance of Wreksodiningrat Bridge, located in the province of Yogyakarta, Indonesia. This bridge is a three spans reinforced concrete arch bridge with a main span length of 75 m and two side spans with a length of 35 m, respectively. This study is a part of a large project carried out by the Ministry of Public Works to study the impact of the new 2016 Indonesia Seismic Design Code for Bridges (SNI 2833:2016). The main objective of this paper is to determine the displacement demands due to earthquake load based on the new seismic code design for bridges, SNI 2833:2016. In addition, demand capacity ratios (D/C) of the main structural components, such as the compression arch and main column (pier) at the fixed support, are also reviewed in this paper. The analysis was carried out using nonlinear modal pushover analysis. The arch bridge modeling is three dimensional, where structural elements such as beams, columns, and compression arches are modeled as frame elements. The plastic hinges are modeled as fiber hinges with unconfined and confined concrete material stress-strain relationship following Mander formula. The analysis result shows that the displacement demands of the bridge are 2.9 cm and 20 cm in the longitudinal and transverse direction, respectively. The D/C ratios of the compression arch due to demand earthquake load are 0.74 and 0.95 in the longitudinal and transverse direction of the bridge, while the D/C ratios of the pier are 0.15 and 0.80 in the longitudinal and transverse direction. Based on the above results, it is concluded that the studied bridge is able to withstand the seismic load requirements in the new Indonesia Seismic Design Code.

The development of codes for the earthquake resistant design of concrete structures in New Zealand since the 1931 Hawke's Bay-earthquake is traced. The background to the developments in the design procedures through the years is discussed. Californian seismic design codes, lessons from past earthquakes, and the results of analytical and experimental research work, much of it conducted
in New Zealand, have led to the current philosophy for seismic design in New Zealand as expressed by the 1976 SANZ loadings cods and the SANZ concrete design code about to be published. These codes state requirements for both adequate strength and ductility, and emphasize the importance of structural detailing to achieve satisfactory performance of structures during severe earthquake loading. This New Zealand seismic design philosophy for concrete building and bridge structures is reviewed. A summary of the seismic design provisions of the new SANZ concrete design code (NZS 3101) is given in an Appendix.

Abstract In an effort to improve the harmonization of the Romanian design codes with the Eurocodes, the revision of the Seismic Design Code, P100-1, started in April 2010 and ended in September 2013. The main issues addressed during the revision process are presented in this paper. They include re-outlining the fundamental requirements for seismic design, revision of the seismic action, improvement of the specific provisions for the design of reinforced concrete, steel, composite, wood and masonry structures and non-structural components. This paper focuses on the specific provisions for reinforced concrete structures but general information about the fundamental requirements and the seismic action are presented as well.

Wenchuan Ms 8.0 Earthquake

During Wenchuan Ms 8.0 earthquake, masonry buildings have suffered severely damaged and collapsed, causing heavy casualties and huge economic losses. In this paper, based on seismic site survey data, some new phenomena and characteristics of earthquake damage in comparison with the 1976 Tangshan earthquake, such as seismic damage of large space buildings, inclined or “X” shaped crack in wall between windows or spandrel wall, stair damage, falling of precast reinforced concrete slab and horizontal crack at the bottom of structure, are discussed in detail. Then, the impact factors of seismic capacity of masonry building in Wenchuan earthquake, including construction age, seismic fortification, bay size, floor (roof) form, layer number, thickness of bearing wall are analyzed, respectively; Finally, some recommendations on seismic design and reconstruction of masonry structure by the seismic design code are proposed.
